Honest Review

Honest review: I had just purchased this only a few days ago so i cant say that this products works for sure. The scent smells really good like peppermint. Surprisingly it does come in a bigger bottle than i was expecting. All you have to do is massage a half inch of this product into your scalp twice daily preferably morning and evening.

Exceptional volumizing!!!

Amazing!! This serum ACTUALLY works! I can't speak to the hair regrowth yet (1st bottle, halfway through), but the volume aspect is impressive! A little bit at the roots at bedtime and I wake up with volumized hair! It works on freshly washed, day 2 or day 3 hair! It does not leave a residue or texture, doesn't leave a noticeable order once it dries/absorbs and the scent is pleasant and light when applying. There are SO MANY TIMES that I've bought beauty products that just don't work, don't do what they advertise and are a complete waste of money. This. Is. The. Exception.

Really lightweight and refreshing

I only use this product once a week and that's right after shampoo and conditioner. I have type 4 hair that is medium porosity but I do struggle with putting heavy oils on my hair and scalp. My hair doesn't like too much buildup and my scalp becomes so tender and sore when I use oils. I find that serums like this one work the best for me. Water based scalp products are more effective than an oil that takes forever to penetrate anyways. This paired with daily scalp massaging throughout the week has made my hair fuller and stronger. Will keep this in my routine!
