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...

It works to promote hair growth
Hair Type Straight Hair
My hair started thinning very rapidly when I hit age 61 (I'm 63 now) (genetic, my mothers hair is very thin when she got older). I have tried a couple topical hair treatments (can't afford the pricey nutrafol). They work but are pretty expensive. This has most of the same ingredients as one of them. Since I started using it my hair on my scalp has grown and is thicker. People have commented that they notice the difference. I put a small amount on my scalp every night, mostly on top where it's thin and rub it in. If you use too much it will make hair greasy. This is a good affordable alternative for hair density.
On my second bottle
Hair Type Very Curly Hair
I have seen hair density serums but have been skeptical. The price was very reasonable and gave it a try. I had some damage to my hair and wanted a fuller hair line. I was also concerned about excessive hair fall in the shower. I am blown away in the hair growth and how much thicker my new growth is. I have been using 3-5 times per week. I see very small amounts of hair fall now in the shower. I also started using on my daughter's edges from wearing braids. I have also caught my husband using it as well around his temples. While it is not instant, I saw a difference when I finished the bottle. I will be keeping this in rotation.
Wowwwww
I see a lot of reviews saying it takes time (and it definitely does) but I feel like I started seeing results VERY fast. For reference I started using this in january and as of march I have seen so much hair growth. Sometimes the growth will be wispy little hairs, and other times I find little tufts of hair like the one in the picture. I will definitely be repurchasing this!

I think it has promise
Hair Type Straight Hair
I have super fine hair. I recently noticed my part appeared to be getting wider & that you could see my scalp around the part. I've used almost a whole 1oz bottle & while I don't see a difference around the part yet, I have seen an influx of baby hairs
Takes time but works WONDERS!
Hair Type Straight Hair
I started using this product 2 years ago and I can say for certain that my hairline in the front is so much thicker. It didn't happen overnight, but I now have new locks of hair where I didn't before. My hair had thinned from years of hard water exposure and from being pulled back into a bun, but this product has helped so much. I also have an oily scalp and this serum does not make me greasy. For best results I would apply onto your wet scalp after a wash, then either air dry or blow dry your hair and the serum will work its magic.
