Not just baby hairs - it works!!
This review is long overdue but given the rate of natural hair growth I wanted to ensure it wasn't just fuzz, baby hairs, or wishful thinking. As you can see I also have some psoriasis on my scalp before I began and still. This product had no affect, neither positive or negative, on the psoriasis ...

DECIEM will not disclose content concentration
This product is in large part marketed on the fact that it contains REDENSYL. There's some clinical evidence that REDENSYL promotes hair growth. However, DECIEM will not disclose the concentration of REDENSYL in this product, making it impossible to compare with alternative products containing the i...

So far great!
Did what I was expecting it to do. It decreased my shedding and I have started to see new growth and hair filling in at temples. It even soothes my scalp. If your expecting a miracle this isn't for you but with consisten use you get some surprisingly positive results.
Meh
No changes noticed after using it consistently daily
I'm purchasing for a second time!
I do see a difference and ordering one for my son.
Love
I've been using this product for about a month now. I've been reasonably consistent. I absolutely see a difference. I have a lot of thinning on my hair line. A lot of breakage and just stringy looking all around. This has added thickness and volume to my hairline and I see a little bit of new growth. My hair looks better in between washes since I've started this as well. I put it on at night and by morning it's completely soaked in and not greasy at all. Great product at a great price.
Worth a try
After using many expensive scalp serums that did nothing except make my hair greasy, Ordinary Scalp Serum is a keeper. Good for sensitive scalp, no fragrance, no irritating ingredients. Only been using a short time, but I will continue to use for increased scalp moisture. Price point is very reasonable. Hint for application: Buy a scalp serum dispenser. It is much easier to use than included eye dropper.
