## Introduction

Individuals engrossed in daily routines or those lacking defined timeframes may inadvertently overlook their personal grooming, leading to prolonged stress. This neglect, compounded by the pressures of modern life, can stimulate cortisol release, consequently amplifying sebum secretion. Elevated cortisol levels, triggered by the hypothalamic-pituitary-adrenal (HPA) axis in response to stressors, play a pivotal role in exacerbating sebum production. Moreover, cortisol's influence extends to heightening sebaceous gland activity, further exacerbating the issue of excessive sebum secretion.
In today's fast-paced professional landscape, career women find themselves engulfed in a whirlwind of activities, leaving little time for personal upkeep. Amidst hectic schedules and demanding responsibilities, the upkeep of hair, a quintessential aspect of personal presentation, often takes a backseat. The allure of well-maintained hair is undeniable, serving as a powerful symbol of confidence and professionalism. However, the reality of balancing career aspirations with personal grooming can be daunting. As such, exploring strategies to streamline hair care routines becomes imperative for career women seeking to exude confidence and competence in their professional endeavors.
Many women find themselves pressed for time to maintain the luster of their locks. Faced with this challenge, they seek out convenient solutions to keep their hair looking fresh and vibrant. Dry shampoo has emerged as a widely embraced hair care solution, offering expedient refreshment and rejuvenation sans the necessity of traditional shampooing rituals. Engineered to absorb surplus oil, grime, and malodor from both scalp and hair, it promises a revitalized appearance characterized by enhanced cleanliness and voluminous texture.
Experts recommend moderation when using dry shampoo, suggesting that it should not be part of someone's daily routine. Excessive usage of dry shampoo can engender a plethora of adversities. These include the accumulation of residue on the scalp, leading to follicular congestion and potential irritation from chemical constituents, precipitating allergic reactions. Moreover, the propensity for dry shampoo to strip away natural oils vital for scalp and hair moisture exacerbates concerns. The incorporation of asbestos fibers and powdered magnesium silicate in some formulations also raises apprehensions regarding respiratory ailments and carcinogenic risks. Given the escalating demand for natural and herbal alternatives in personal care routines, there arises a compelling need for herbal dry shampoo formulations.
The efficacy of aloe vera in addressing the challenges of greasy hair stems from its potent enzyme content, notably lipases. Renowned for its lipid-dissolving properties, aloe vera aids in the breakdown of fats, sebum, and residues lingering on the scalp, thereby mitigating scalp and hair oiliness without compromising hair integrity (Zaid et al., 2017). Lipases, integral enzymes found within aloe vera, play a pivotal role in this process by catalyzing the breakdown of fats and oils, thereby regulating excessive oil accumulation on both scalp and hair. This inherent attribute of aloe vera not only proves efficacious in managing oily hair but also fosters scalp wellness by curbing greasiness and preserving an optimal oil equilibrium on the scalp (Zaid et al., 2017).
Extracted from botanical species such as Cymbopogon citratus and Cymbopogon flexuosus, lemongrass essential oil boasts citral as its primary constituent. Renowned for its potent antimicrobial and antiseptic attributes, citral renders lemongrass oil a formidable ally in combatting scalp irritations while fortifying hair follicles. Furthermore, when combined synergistically with essential oils like rosemary and lavender, lemongrass oil demonstrates remarkable efficacy in addressing hair loss, ameliorating split ends, and nurturing scalp and hair vitality by mitigating greasiness, dandruff, and inflammation instigated by deleterious microorganisms. The antimicrobial prowess and soothing capabilities inherent to lemongrass oil position it as a prized natural remedy for an array of scalp maladies, thereby fostering hair resilience, radiance, and overall scalp well-being.
The objective study of this study is an investigation into the potential lipase content in aloe vera combined with citral as an ingredient in lemongrass which can be the main ingredient in herbal-based dry shampoo. This makes the main focus in solving problems regarding the contents of dry shampoo which cannot be used on a daily basis. Apart from that, there are no or very few dry shampoo formulations based on herbal ingredients. With the implementation of this study, dry shampoo with basic ingredients of aloe vera and lemongrass helps develop dry shampoo that is safer and more effective in reducing sebum production in hair, creating eco-friendly products. friendly, and can be used as an alternative in the cosmetics industry.

## Materials and Methods
### Material Collection

All powdered materials were purchased from Sigma-Aldrich Company, USA in Indonesia.

### Formulation of Herbal Dry Shampoo

All materials were mixed in different proportions to obtain the formulas listed in Table 1. Formulation development for this study was based on formulations provided by leading commercial manufacturers of dry shampoo, as referenced from reputable sources such as DSM Nutritional Products, Switzerland (haircare-formulation-alp-dry-shampoo.pdf (dsm.com)) and J. Rettenmaier & Sohne, Germany (Formulation Dry Shampoo (jrs.eu)), both renowned for their excellence in product development and innovation in the field. The materials were first manually ground using a mortar and pestle until a sufficient level of homogeneity was achieved.

### Homogeneity Test

This study used a 100x microscopic magnification to evaluate the homogeneity of dry herbal shampoo for oily hair. Three different formulations with different concentrations of powdered aloe vera extract and lemongrass as active components were investigated. Formula I showed a relatively uniform level despite having fewer active components. Formula II demonstrated a moderate level of homogeneity, with a medium number of active components. Curiously, formula III showed a slightly heterogeneous level, although having more active components than formula I and II. All formulations satisfied the homogeneity test requirements in spite of this variance in homogeneity levels.

The study aimed to assess the oil absorption efficacy of dry herbal shampoo for greasy hair using an in vitro oily hair model, observed under a microscope at 100x magnification. Three formulations were tested, labeled as FI, FII, and FIII. The results revealed that FI still left the hair oily, although there was a slight decrease in the amount of oil. FII resulted in slightly oily hair, while FIII effectively reduced oiliness, leaving the hair non-oily. These findings suggest that FIII is the most effective in reducing oiliness, followed by FII, with FI showing the least effectiveness. Understanding the oil absorption properties of herbal shampoos is crucial for developing effective products for greasy hair.

## Discussion
### Formulation of Dry Herbal Shampoo

A dry herbal shampoo was developed by combining specific quantities of ingredients as detailed in Table 1. The key active ingredients, aloe vera and lemongrass, contain phytochemicals that are highly beneficial for improving greasy hair. As the shampoo is intended for spray application, it was essential to ensure good flow properties to enhance spray performance for convenient use on the scalp. Aerosil at 5% was utilized to improve flow characteristics in all formulations. Additionally, tapioca starch was included to absorb excess oil from the scalp and hair, while talcum was used to make the hair smoother and easier to comb. Magnesium stearate acted as an anti-clumping agent, preventing the herbal dry shampoo ingredients from clumping. Vivapur was incorporated to bind sweat and moisture, helping to keep the hair hydrated. Preservatives such as nipagin and nipasol were used due to the natural ingredients. These ingredients not only provide texture to the hair but also help maintain hair volume. The final formula of the prepared shampoo is summarized in Table 1.
Aloe vera is a popular choice for hair care products due to its soothing and moisturizing properties. It contains enzymes that break down fats, helping to remove excess sebum and control greasiness. Rich in antioxidants and vitamins A, B12, C, and E, aloe vera strengthens hair follicles, promotes healthy growth, and nourishes the scalp. Its ability to cleanse efficiently removes oil and residue without stripping moisture. Additionally, its antibacterial properties maintain scalp health without damaging hair, making it a valuable ingredient in dry herbal shampoos for greasy hair.
Lemongrass, known for its aromatic properties, is rich in phenolic metabolites, terpenoids, alkaloids, and volatile compounds, all with potent antioxidant and antimicrobial effects. Its pharmacological action on greasy hair includes reducing sebum production, controlling fungal growth, providing antioxidant protection, and improving scalp health. These properties make lemongrass a valuable ingredient in dry herbal shampoos for managing greasy hair and scalp conditions.

### Dry Herbal Shampoo Evaluation

The comparative effectiveness of the three formulated herbal dry shampoos was evaluated through a series of physicochemical tests. The results of these tests are discussed in detail below.

### Organoleptic Test

The excipient components used in the formulation tend to be white in color, hence the product's color depends on the composition of the active ingredients, namely powdered lemongrass and aloe vera, which impart a green hue. Interestingly, the combination of these two ingredients does not provide a strong, distinctive aroma; the aloe vera is less aromatic, while the characteristic scent of lemongrass gives the combination a scent reminiscent of matcha. Furthermore, the manufacturing process, which involves gradual manual grinding followed by filtration using a Laboratory Standard Test Sieve with a mesh size of 0.075 mm, yields a product with an optimal level of fine texture. Continuous, gradual mixing is performed until a sufficiently homogeneous mixture is achieved, both organoleptically and microscopically, resulting in a powder that appears homogeneous despite the presence of minor aggregates or flocs.

### pH Determination

In order to identify whether dry herbal shampoo for greasy hair is within the ideal pH range for hair care, it is crucial to perform a pH assessment. Keeping the pH balance right is essential for having healthy hair and scalp. The cuticle layer is helped to contract by dry herbal shampoos with a slightly acidic pH, ideally <5.5, which reduces frizz and moisture loss. Dry herbal shampoo's pH should be assessed to make sure it is not too harsh on the hair and scalp, supporting general hair health and averting potential harm from utilizing products that aren't pH-leveled correctly.
Dry herbal shampoos with an improper pH level can upset the natural pH balance of the scalp and hair, leading to unfavorable outcomes like breakage, dryness, and damage to the hair strands. In people who are prone to seborrheic dermatitis and have oily hair in particular, this imbalance can cause irritation, itching, and inflammation. Additionally, having hair with an improper pH can make it more difficult to manage and style by increasing frizz and static electricity. The hair cuticle may become rougher, more porous, and more prone to breakage and split ends as a result of shampoos with pH levels that are outside of the ideal range.
The mildly acidic qualities of aloe vera and lemongrass are well-known for their ability to balance the pH of the scalp, lessen excessive oiliness, and support healthy hair. The pH of formula III stays within the intended range while having a higher concentration of active components, indicating that the formulation is appropriate for oily hair. A lower concentration of active components could be the reason for Formula I's higher pH, which suggests it might not meet the standards. It may be even more effective for oily hair if the formulation is changed to preserve a slightly acidic pH. Particularly for people with oily hair, Formula III's slightly acidic pH due to increased concentration of active substances can help with better cleansing, conditioning, and general hair health advantages.

### Spray Distance Test

The spray distance test can be used to evaluate the performance of dry herbal shampoo sprays for Normal to Oily Hair. This test can help determine the coverage, distribution, and effectiveness of the shampoo in absorbing excess oil and impurities from the hair and scalp. By measuring the distance at which the shampoo particles are evenly distributed, the test can provide valuable insights into the product's performance and help optimize the formulation for better oil absorption and improved overall effectiveness.
The risks associated with using propellants in hair care products, including flammability, inhalation hazards, and potential carcinogenicity, highlight the need for safer alternatives. In this study, we addressed these concerns by developing a dry herbal shampoo with a propellant-free spray application method. Our innovative approach utilizes a special prime packaging design that harnesses the force of ambient air to fill the interior of the package, facilitating the dispensing of the product for hair application. By eliminating the need for propellants, our packaging design not only optimizes the application process but also reduces the risks associated with propellant exposure. This propellant-free spray packaging not only enhances product safety for consumers and hair stylists but also contributes to environmental sustainability by reducing the release of volatile organic compounds (VOCs) into the atmosphere. This research underscores our commitment to developing safer and more environmentally friendly hair care products.

### Homogeneity Test

An essential component of assessing the quality of herbal dry shampoo formula is the homogeneity test. This test makes that there are no lumps, flocculates, or aggregates in the shampoo's composition and that it is dispersed evenly. A useful understanding of the efficacy and performance of the shampoo can be gained from the homogeneity test findings.
All formulations met the homogeneity test requirements despite formula III's heterogeneous level, suggesting that the variance in homogeneity levels may not have a substantial impact on the formulation's efficacy or performance. This implies that the content of the formulation, including the active components' particle size and distribution, as well as the method of manufacture employed to make the dry herbal shampoo, can have an impact on the heterogeneous level seen in formula III.
The presence of aggregates or flocules in formulations II and III, which have medium and greater concentrations of aloe vera extract powder and lemongrass, respectively, as active components, suggests a propensity toward aggregation. The greater concentration of active substances in these formulae may be the cause of this phenomena. Aggregates or flocules are more likely to form when there are more active substances present because of the increased probability of particle interactions. Because they produce concentrated, localized pockets of increased concentration within the formulation, these aggregates may lead to a less homogenous mixture. To ensure the quality and effectiveness of the product, it is essential to comprehend the factors that affect aggregation in herbal shampoo formulations.

### Oil Absorption Test

The study's findings demonstrate the varying effectiveness of the three formulations (FI, FII, and FIII) in absorbing oil from greasy hair. FI, which has the lowest concentration of active ingredients, showed limited effectiveness in reducing oiliness, leaving the hair still oily. FII, with a medium concentration of active ingredients, performed better than FI but only managed to partially reduce oiliness, resulting in slightly oily hair. In contrast, FIII, containing the highest concentration of active ingredients, was the most effective in reducing oiliness, leaving the hair non-oily. Moreover, FIII not only absorbed excess oil but also provided thorough nourishment by coating the entire hair shaft. This is in contrast to FII, which only coated certain hair structures with less-than-optimal absorption. These results highlight the importance of the concentration and composition of active ingredients in dry herbal shampoos for effectively managing greasy hair. Understanding these factors is essential for developing herbal shampoos that not only absorb excess oil but also nourish the hair, providing a holistic solution for greasy hair-related issues. Additionally, the study can guide the development of new formulations by optimizing their concentrations to achieve better oil absorption and improved effectiveness in managing greasy hair.
In the formulations tested (FI, FII, and FIII), starch was included in all three formulas at the same concentration. However, in FI, which contained a lower amount of lemongrass and aloe vera powder extract, the starch alone was not effective in reducing oiliness, as the overall formulation lacked sufficient active ingredients to achieve optimal oil absorption. However, natural starches, such as corn starch and rice starch that are used on the formulation, play a crucial role in enhancing the oil absorption properties of the shampoo, as they bind to the oil and other impurities on the hair and scalp, reducing oiliness and providing a cleaner appearance. Starch functions as a natural absorbent, binding to the oil and other impurities on the hair and scalp, thereby reducing oiliness and providing a cleaner appearance. When combined with lemongrass and aloe vera powder extract, which have additional beneficial properties for the hair and scalp, starch enhances the overall effectiveness of the shampoo. This highlights the importance of a balanced formulation, where each ingredient complements the others to achieve the desired results.

## Conclusion

The developed dry herbal shampoo formulations, containing aloe vera and lemongrass as key active ingredients, offer promising solutions for managing greasy hair. The inclusion of Aerosil for improved flow, tapioca starch for oil absorption, talcum for hair smoothness, and magnesium stearate for anti-clumping properties enhances the efficacy and user experience of the shampoo. The evaluation of the formulations through various tests highlights their potential in providing effective cleansing, conditioning, and oil absorption properties for greasy hair.
Formula III, with a higher concentration of aloe vera and lemongrass extract powders, demonstrated superior performance in reducing oiliness and providing nourishment to the hair, compared to Formulas I and II. The slightly acidic pH of Formula III, attributed to the increased concentration of active ingredients, further supports its suitability for oily hair, as it helps balance the scalp's pH and maintain hair health.
The innovative propellant-free spray packaging design offers a safer alternative for application, reducing environmental impact and health risks associated with traditional propellant-based sprays.
Overall, the study underscores the importance of formulation composition and concentration in developing effective dry herbal shampoos for greasy hair. Future research could focus on optimizing the formulations for enhanced oil absorption and nourishment, as well as exploring additional natural ingredients for improved hair health benefits.
