While we designed the formula of the hair oil in a way for it to be suitable to be used during pregnancy by researching the ingredients thoroughly and taking into consideration the recommended guidelines on what is safe to use whilst being pregnant, the hair oil includes a total concentration of 1% of essential oils. Due to the incorporation of essential oils, we recommend checking with your doctor prior to using the hair oil, especially whilst pregnant, breast-feeding, or suffering from pre-existing health conditions.
