No minoxidil. No finasteride. No hormones. No silicones. Every active is listed on the label. Dermatologist formulated, made in a GMP certified facility.
How it works+
DHT raises cortisol in the scalp. Cortisol creates an inflammatory barrier that blocks amino acids from reaching the follicle. The follicle starves, shrinks and goes dormant. Most growth molecules are too big to get past that barrier, so they sit on top and wash off. FST-5's peptides are 340 to 888 Daltons, small enough to pass 4 mm down to the follicle root, where they calm the inflammation, restart the growth signal and extend the growth phase. Aminexil keeps the collagen around the root flexible, so every new hair stays anchored.
How to use+
One full dropper along your part, or wherever you are thinning, once a day, ideally at night or after a shower. Wet or dry scalp both work. Massage in for 30 seconds. It absorbs in about 20 seconds with no residue and no smell, so you can style as normal. Missed a night? Just continue the next one; the follicle cycle runs over weeks, not hours.
100-day money-back guarantee+

Made for women and men

Same follicle. Same signal. Same bottle.

Thinning starts the same way in everyone: the follicle stops getting its growth signal and shrinks. FST-5 restores that signal, so it works whether your trigger was hormones, stress, weight loss or genetics.

Woman applying FST-5 along her part

For women

Widening part, thinner ponytail, clumps in the drain.

  • Postpartum and menopause related shedding
  • Hair loss during GLP-1 weight loss
  • Diffuse thinning across the top and the part line
  • No hormones, so it fits alongside anything you already take

For men

Thinning crown, receding temples, scalp under the bathroom light.

  • Early to moderate crown and hairline thinning
  • An alternative to minoxidil, without the dread shed when you stop
  • Stacks with finasteride or minoxidil if you already use them
  • One dropper in the morning routine, no foam, no residue
Animation of peptides reaching the follicle root

Why most serums never reach the follicle

The root sits 4 mm down. Most molecules stop at the surface.

Your follicle root is buried under a barrier that most hair-growth ingredients cannot cross. They sit on top and wash off in the shower. FST-5 is built around the one class of molecule small enough to get through.

  1. DHT raises cortisol in the scalp

    Cortisol creates inflammation that blocks amino acids from reaching the follicle. The follicle starves, shrinks and goes dormant.

  2. Peptides pass the barrier

    FST-5's three signaling peptides are 340 to 888 Daltons, small enough to travel 4 mm down to the root. Once there, they calm the inflammation and restart the growth signal.

  3. The growth phase gets longer

    Each hair grows longer and thicker before it sheds. Shedding slows first, then density builds.

  4. Aminexil anchors the new hair

    2% aminexil keeps the collagen around the root flexible, so the hairs you regrow stay put instead of falling out in the shower.

What to expect

Peptides are a restoration, not a paint job. Here is the order things come back in.

Hair grows about half an inch a month, so density is the last thing you see, not the first.

WEEK 1 TO 2

The drain gets cleaner

Less hair on the pillow and in the brush. The scalp feels calmer.

WEEK 2 TO 4

Shedding stops

The first baby hairs start sprouting along the hairline and crown.

WEEK 4 TO 12

New hairs thicken and darken

You stop seeing scalp under the bathroom light. The ponytail feels fuller, the crown stands up.

MONTH 3 TO 5

Density you can see in photos

Hair you can no longer see through. Most people are here by the end of the 5-bottle bundle.

Results

What 12 weeks of one dropper a night looks like, in their words

Written by customers who had tried the oils, the foams and the gummies first.

Ever since menopause, over 6 years ago, my hair has been thinning. Constantly finding it on my pillow and in the drain and seeing more and more of my scalp every month. I put one dropper along my part at night, and after about 5 weeks the shedding just stopped. Now at 4 months I have baby hairs sprouting everywhere and you can no longer see my scalp.

Been using this for 2 months and my drain is clean. Hairline is filling in too like I dont see scalp at my crown anymore. Used to be I would wash my hair and bam, a whole clump in the drain. Tried rogaine before and honestly it made me shed worse and my scalp burned. The biotin gummies from the drugstore did nothing except make my nails grow.

I didn't expect it to work because I've tried oils, foams, vitamins, the expensive salon ampoules. Minoxidil left my hair greasy and my pillow stained. So I went into this completely not expecting it to work. It's light, absorbs in seconds, and after about 3 weeks I noticed way less hair in my brush. At 10 weeks I have real baby hairs along my forehead and my stylist asked what I'd changed.

Questions

Good to know before you start

Anything else, write to support@richvell.com. A person reads every email.

I have already tried hair growth products and they did nothing. Why would this be different?+

Because what you tried was almost certainly water, alcohol and a molecule too big to get past your skin, or a vitamin that went through your gut and never reached your scalp. Your follicle root sits 4 mm down. Anything over about 500 Daltons stays on the surface. FST-5's peptides are 340 to 888 Daltons, small enough to reach the root.

Does it work for women and men?+

Yes. It is applied to the scalp and works on the follicle signal, which is the same in everyone. Women use it for postpartum, menopause and GLP-1 related shedding and diffuse thinning. Men use it for a thinning crown and receding hairline.

How long before I actually notice something?+

Most people notice less shedding in the first 2 to 3 weeks. Baby hairs at the hairline and less scalp showing usually appear between week 4 and week 8. Full density takes 3 to 5 months, because hair only grows about half an inch a month. Give it 100 days. If nothing changed, we refund you.

Will it make my hair greasy or mess with my styling?+

No. FST-5 is a light, watery serum, not an oil or a foam. One dropper along your part absorbs in about 20 seconds. No residue, no smell, no stained pillowcases. Apply it at night or after a shower and style as normal.

Is 2% aminexil safe? I have a sensitive scalp.+

Yes. Aminexil has been used in salon hair-loss ampoules for over 20 years at 1.5%. FST-5 uses 2% alongside soothing botanicals like centella, licorice and aloe. There is no minoxidil, no alcohol burn and no hormones. If your scalp is very reactive, start with half a dropper for the first few nights and build up.

Can I use it with minoxidil, finasteride or my other products?+

Yes. FST-5 works on a different pathway, the follicle signal rather than blood flow or hormones, so it stacks with anything you already use. Many people use it to come off minoxidil without the dread shed: keep both for 4 weeks, then taper the minoxidil. It is fine with shampoos, oils and supplements.

What if I miss a night?+

Nothing bad happens. The peptides work on the follicle's growth cycle, which runs over weeks, not hours. Missing one or two nights will not undo your progress. Just start again the next night.

How do automatic refills work?+

With automatic refills your bundle ships again on schedule at 33% off: one bottle every 28 days on the single bottle, two bottles every 2 months on the 3-bottle pack, and three bottles every 3 months on the 5-bottle pack. Pause or cancel any time from your customer portal or by emailing us.
