The Age group between 20 to 35 is known as the age of Pitta (heat). This excess heat damages & destroys the hair follicle and causes hair fall and premature greying. Instead of trying external applications, you should start taking heat-reducing diets and herbal formulas. This can significantly help to calm down the heat and nourish the hair follicles. If you take the right step under the proper guidance of an Ayushakti expert, at this age you can even grow back your lost hair in just a few months.
