The science, made simple.
A quick guide to what's in your bottle and how it cares for your hair.
What is a serum?
A serum is a light, concentrated formula made to absorb. Unlike heavy oils or rinse-off treatments, it sinks right into the scalp, so there's no greasy feel and nothing to wash out.
What is a peptide?
Peptides are short chains of amino acids, the same building blocks that make up keratin, the protein your hair is made of. Ours are copper tripeptide-1 and biotinoyl tripeptide-1.
Each bead is an amino acid. Link a few together and you get a peptide.

“My scalp used to feel tight and dry by the end of the day. Massaging the serum in with the comb is so soothing, and it has become my favorite part of winding down. My hair has a lovely shine to it now.” -
Michelle, 38
“I got the comb and three bottles to share with my sister. We both love how relaxing the massage feels and how soft our hair is afterwards. Simple, pretty and genuinely nice to use every day.” -
Megan, 29
“The serum has a light, clean feel and sinks in quickly. I use it after my shower and my lengths feel softer and look glossier. The packaging is gorgeous too, so it lives on my vanity now.” -
Hannah, 34
“I look forward to my two-minute scalp routine every night now. The comb makes it feel like a little spa moment, and the serum doesn't leave my roots greasy. My hair looks shinier by morning and I actually enjoy the ritual instead of rushing through it.” -
Priya, 41
“I wasn't sure about a comb with a built-in reservoir, but it's so easy. Fill it, glide it along your parting and you're done. No drips on my pillow and no mess on my hands. My hair has felt softer and smoother since I started.”

Takes A Minute, Then I’m Done
I’m pretty lazy with hair products, honestly. I keep this next to my toothbrush so I remember to use it. Takes a minute, and then I’m done.

No Need To Wash It Out
I like that I don’t have to wash it out. I usually put it on at night and just leave it. Really easy to fit into what I already do.

Makes That Part So Much Easier
The oily hands were what annoyed me most about using scalp products. Using the Miiley serum with the comb makes that part so much easier.

Consistent With It For A Month
I’ve been pretty consistent with it for a month. The biggest thing I’ve noticed is the little hairs coming in around the front when I pull my hair back.
