great if you wanna just keep buying more and never actually moisturize
Scent: Aloe & White Tea, Size: 16 Fl Oz (Pack of 1)
this is the least moisturizing lotion I have ever used in my entire life. it goes on so thick and smooth and feels great and smells great but then a couple hours later my skin feels dry and needs more.. and if you put it on at night, when you wake up the next morning, your skin is completely ashy and flaky. It’s absolutely awful.

Good product - great ingredients.
This keeps my scalp very clear. And I dont use it every time. I do leave it on for a few mins when I use it.

MUST READ - HONEST REVIEW
I want to share as much as I can about this product - only honest reviews from me. I bought this product because I had been experiencing dry and itchy scalp. This has been going on for several years. I tried many things. And I mean MANY. From increasing my water intake to several over the counter products. I simply couldn't understand what was going on to cause this embarrassing and uncomfortable experience. I'm a very clean person and as embarrassing as it is to say this, I want to be honest... my problem got to the point of developing a scalp odor. Nothing worked. Nothing. Finally, I came across this shampoo. I actually bought several different products for my scalp from Amazon the same day I bought this shampoo. I figured I can't give up! Needless to say, I can't speak for the other products because this one did the trick!! It really did!! No more itchy scalp. No more flakes and dryness. NO MORE EMBARRASSING ODOR!! You don't know how much a person can honestly appreciate this result until you yourself have lived with the humiliation of this problem. Application: I am very generous when applying this shampoo. In the shower, I place plenty in my palm, lather it in my hair for a good minute. I leave it in while I wash and scrub my body. I rinse then repeat. The second time around I only lather, gently scrubbing my scalp and immediately rinse. No waiting. Done. If you've ever felt "soft water", my personal experience has been that after rinsing the shampoo off, my hair feels so soft, as if I had run soft water through it. I will also add the only downfall is that I sometimes do feel a slight residue-like feeling on my hair after it dries. That's pretty much it. But hey, I can totally live with that as oppose to the ladder! It's probably a simple matter of figuring out the proper portion to use. Did I mention my hair is long, all the way down to my hips. Hence the generous portions. Over all, this shampoo deserves an honest 5 star rating from me. Try it! See for yourself. Hopefully your experience will be as great as mine, if not better!

This could be the answer to seborrheic dermatitis/excessively oil skin/scalp
I struggle with seborrheic dermatitis and excessively oil skin/scalp. This causes greasy hair, itchy, flaky and tender scalp. I've been looking for a simple and low maintenance scalp/hair care routine for the past 2 years. Switching between shampoos, oils, natural remedies, prescriptions and still not much result. I started to experience excessive hair loss too because I was constantly scratching and picking at the flakes. I came across Puriya 2 weeks ago and decided to give it a try. The directions says to use it everyday for 2 weeks and then gradually decrease. I wasn't very thrilled about shampooing my scalp everyday since I have fine, curly hair and excessive oil production and constant washing increase the oil production. But I decided to follow directions and I started to notice less flakes after day 3. My scalp is much less itchy and greasy. The flakes have decreased and are dry vs. greasy. The shampoo also has not dried out my hair. I try not to lather my hair and keep the shampoo on my scalp and massage for a few minutes. I'm going to continue to use it until the bottle is empty and see if the results remain the same or better. For now, I am really excited that this is working for a lifelong nuisance.
