Works at the root
Zero glaucoma drugsMoney back at week 12Tap every one that's you
- My set came off and my lashes were short and stubby
- I have a bald patch in the outer corner
- I keep booking fills just to hide what's underneath
- I tried castor oil for weeks and nothing changed
- I'm scared of the famous serum after reading about dark lids
If you tapped even one, none of it is your fault. Here's what's really going on.
The real reasonYour lashes didn't stop growing. They never got to finish.
Every lash grows from a root under the skin for about 90 days. Then it rests, falls out, and a new one starts.
Extensions hang glue and weight on each lash, so it gets pulled out early, before it's done. Do that every 3 weeks for a few years and you're left with short, half-grown lashes.
Think of a lawn that gets mowed every day. The roots are fine. Nothing ever gets the time to grow tall. Give the root what it needs for one full cycle and the lash grows all the way out.
Why nothing you tried worked
Every one of these works on the surface. Your lashes grow from the root.
One swipe at the root, where lashes grow. Two lash peptides at full strength keep each lash growing until it's done. No drug, so nothing to lose when you slow down.Feed the root, not the tips, for one full lash cycle. That's the whole secret, and it's about 12 weeks.

Week 0 vs week 12
Three years of extensions. When my lash girl moved away I took them off myself and there was basically nothing left underneath. I wore glasses to work for a month so nobody would notice. Week 4 I stopped finding lashes on my pillow. Week 8 the bald spot on my left eye was gone. By week 9 I stopped booking fills, and I haven't been back. I still take the photo every Sunday because I can't believe it. 😭😭
My lifts left my lashes straight and brittle. They stopped breaking in two weeks. Honestly I didn't see longer lashes until week 6 and almost quit, so be patient. Week 12 is the photo I show everyone.
I had a bald spot in the outer corner from a bad removal. It's filled in. I didn't think that was possible without a salon.
I'm a nurse and I read every label. No prostaglandin was the whole reason I tried it. Week 8 my patients complimented my mascara. I wasn't wearing any.
I did the famous one, got the dark lids, stopped, lost everything. This took longer and I don't care, because I get to keep them.

Then keep them
Lashes keep cycling. Stop cold and they drift back. About 3 nights a week keeps them, and one serum lasts another 12 weeks at that pace. That's why Grow + Keep comes with a second serum.

Can I start right after removal?
Yes. Start the night your extensions come off. It's safe with a lift or extensions too.
Sensitive eyes or contacts?
No prostaglandins and no fragrance. Prostaglandin serums use a drug first made for glaucoma, which can darken lids and hollow out the eyes. comeback uses peptides instead. Take contacts out, apply, and put them back in after 15 minutes.
How long does one serum last?
12 weeks used every night to grow. About 12 more weeks at 3 nights a week to keep.
