- Q
Can this product be used on kids?
- Asked by Amanda
- Official Answer By The Ordinary - Brand EngageThe Ordinary's products are intended for adult skin. Though we have no reason to think that The Ordinary's products would be harmful for young people, less mature/younger skin is often more sensitive and frequently changing. For young people we recommend a simple routine of cleansing and hydrating as we do not want to interfere with skin development. For persistent skin issues or specific concerns, we suggest consulting with your doctor/dermatologist about safe and suitable treatments.Was this answer helpful to you
- Q
Can this be used with minoxidil?
- Asked by Rene
- Official Answer By The Ordinary - Brand EngageHey there. Unfortunately, it is difficult for us to comment on the pairing of our products with those of other brands. We recommend consulting with your doctor/dermatologist, gradually incorporating one new product into your regimen at a time, and applying test patches first to see what works best for your skin.Was this answer helpful to you

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...

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.
Buying a second time
When I went into the salon this week my stylisr remarked about the amount of roots i had and felt it was much more growth than when I usually come in. I have not noticed an increase in thickness - just maybe a bit faster growth
Holy cow this stuff is good 👍🏼
I love this product!!!! Soo satisfying to find something thst ACTUALLY works! This product was made for me < 3
