I was able to grow my eyebrows back in about three months and my hair line has also made a spectacular comeback! I highly recommend and will continue ordering this fantastic potion.

PTD-DBM (Protein Transduction Domain-Fused Dishevelled Binding Motif)
the follicle wake-up
A part looks wider when more follicles along it are resting at the same time. PTD-DBM is built to help a resting follicle start a new growth cycle. In mice, it restarted hair growth.

GHK-Cu (Copper Tripeptide-1)
the growth signal
A resting follicle isn't filling in the line. GHK-Cu signals the growth phase. More follicles growing along the part is what makes it look fuller.

AHK-Cu (L-Alanyl-L-Histidyl-L-Lysine Copper)
the root strengthener
Strands along the part can come in finer, so more scalp shows through. AHK-Cu, the second copper peptide, helped follicles grow longer in lab research on human hair follicles.

-
resting follicle
a follicle stuck resting.
Every follicle cycles: grow, rest, shed, repeat. Stress, hormones, menopause and age can keep more of them resting for longer, and the hair they would grow never shows up. This one is resting.
-
serum arrives
pal-ahkthe follicle protector
one drop, straight onto the scalp.
Bloom is water-based, so it goes on the scalp, not the strand. Pal-AHK carries a fatty-acid tail, a common way to help a peptide stay stable and move into skin. Its job: help protect and repair the follicle.
-
wake-up signal
ptd-dbmthe follicle wake-up
the switch that starts a new cycle.
Follicles start a new growth cycle through a signaling route called Wnt. A protein called CXXC5 holds that route back. PTD-DBM is built to block CXXC5 so the signal gets through. In mice, it restarted hair growth.
-
growth signal
ghk-cuthe growth signal
the copper peptide your body makes less of.
At the base of every follicle sit dermal papilla cells, which set how long it grows. GHK-Cu is a copper peptide the body makes less of with age. In lab research it supports those cells and the blood supply around them. It's also why the serum is blue.
-
growth phase
ahk-cuthe root strengthener
a stronger root.
The second copper peptide. On human hair follicles in the lab, AHK-Cu helped dermal papilla cells multiply and follicles lengthen.
-

acetyl tetrapeptide-3the anchor
a hair that holds on.
A new hair needs a firm hold. Acetyl Tetrapeptide-3 supports the proteins around the follicle that keep hair anchored in place.

Def try this!!
I was previously using an injectable ghk-cu but it would irritate my skin. It wasn't something I wanted to continue long term. I kept seeing ads for fleur so I decided to try it. I'm so glad I did. I don't shed anymore my hair looks and feels thicker and I'm getting baby hairs all over. Just started my second month!

Mixed opinions
I’ve been using this product for 3 mo now and really haven’t seen any changes in my hair! One thing I’ve noticed as I’ve purchased a few times, the product is different between bottles. I’ve received clear serums and then some are blue. Not consistent, just curious why they differ! They should all be clear or all be blue! Makes me unsure of the product.

Our first version of Bloom (1.0) had lower levels of GHK-Cu and AHK-Cu, the two peptides that make the serum blue, so it only looked blue in volume. Bloom 2.0 carries much more of both, so it reads deep blue in the dropper. 1.0 is fully phased out; every bottle now ships as 2.0.
fair questions.
will it get in the way of my styling?
No. It goes on the scalp, not the lengths, and leaves no build-up. Damp or dry hair, nothing to rinse.
will it make an oily scalp worse?
It's water-based with no oil, and leaves no residue.
how long does a bottle last?
One month. 30 ml, about 1 ml a day.
how do I use it?
Once a day, morning or night. Shake, part your hair, apply along the parts and thinner areas, then massage in with your fingertips. About two minutes. Don't rinse.
Patch test first if your scalp is sensitive.
how long before I notice anything?
Hair grows slowly, so we recommend 3–6 months of consistent daily use. Judge it by month three, not week three.
what if it isn't for me?
Your first order comes with 30-day returns. Subscriptions ship free and you can pause or cancel anytime from your account.
