Excellent For Dry Scalp
For someone who has had a dry scalp condition since birth, this product works extremely well. I put it on at nighttime and when I wake up, my scalp has far less flakes than it had last night. I do this daily and there has been a huge reduction in itching, redness and flakiness.

Absolutely terrible for me, personally.

I possibly have fungal acne, so if you have it I would...

I possibly have fungal acne, so if you have it I would definitely avoid it. Coconut oil does the same thing to me.
