You can try essential oils by Anveya

you can use St Botanica`s Oils. For some scalp benefit, hair growth, fragrance, and calming effects, add oil to hair products. For example, you can add a little lavender oil to shampoo, conditioner, or another product. Be sparing. Only add about five drops per ounce of product to be safe.
