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.

Hair Type Very Curly Hair
Its an awesome product
Helped my hair stop falling out within a month
Hair Type Wavy Hair
Been losing hair like crazy due to some health issues but after a month of using this my hair loss has decreased significantly and even noticing new baby hairs all over
AMAZING
I just started using this serum two weeks ago. After applying it consistently 3-4 times a week, I can already tell the difference in density and health. Apply it directly on your snap and massage through. I dont feel like it makes my hair excessively greasy, as someone who already has somewhat greasy hair.. its nothing dry shampoo cant handle!! Reminder: you're not going to see growth specifically with this. This serum is to improve the health of your follicles and promote density. However if you think about it HEALTHY SCALP = HEALTHY GROWTH 😃
Never leave reviews, but needed to for this!
Hair Type Wavy Hair
Been using this serum since Dec 2025 & the biggest difference I'm seeing is that it has decreased hair fall out by almost half! Haven't noticed baby hairs but my hair is growing length wise! Also use it with the Abbey Yung method & my hair loves it
It works very well for me
I have natural type 4 hair. I have been battling with traction alopecia for about 10 years. And my hairline is filling in very nicely. I'm so pleased. My advice is to stop the high tension hairstyles ASAP. Use this on your edges. Keep your scalp clean have a good routine and massage your scalp as much as possible. Take your vitamins drink your water and have a good diet.

How long should the bottle last; am wondering about auto ship timeframe
- Asked by Becki
- Official Answer By The Ordinary - Brand EngageHi there, this depends on how much you use and how frequently. We'd recommend going through one bottle and basing your auto-ship timeframe on that. Typically, with daily use, and a few drops added to the scalp daily, a bottle may last around 2-3 months. We hope this helps!Was this answer helpful to you
