This product is amazing. I have psoriasis of the scalp which can become itchy, inflamed and painful. This keeps my scalp in balance and keeps it from getting too out of control and unmanageable. I still have some light dryness which I combat with a weekly tea tree oil treatment. I use this scalp serum daily in combo with this brands fine hair shampoo and I’ve seen a noticeable improvement in just one month in hair shine, texture, grow th, and scalp comfort. It smells so wonderful. I’ll be making this a part of my hair care routine. I love how there’s no residual grease or oil left on the hair.
