Why it works

Get thicker, stronger hair, fast.

Most hair products coat the strand and wash out by morning. Manefold goes where your hair begins, with five peptides and six botanicals built to support growth at the root.

  • Peptides that go to the root Five signal peptides (bFGF, VEGF, aFGF and IGF-type) support natural hair growth where it starts: the follicle.
  • Strands that look thicker and stronger Arginine with soybean and wheat germ extracts for hair that looks fuller, feels stronger and holds its shape.
  • A scalp that stays balanced Saw palmetto, scutellaria root, rosemary and eucalyptus keep the scalp nourished, refreshed and ready to grow.
  • Water-based, so it actually gets there No heavy oils sitting on your hair. It absorbs into the scalp in seconds, leaves in, and works all day.
  • Sixty seconds a day Results come from consistency. We made it so easy you'll never skip it. Fuller-looking hair in 3-6 months.

The 60-second ritual.

Once a day, on a dry or towel-dried scalp. Keep it next to your toothbrush and you won't forget.

Step one

Part

Part your hair where you want it to look fuller: crown, hairline, temples.

Step two

Drop

Apply a few drops directly to the scalp. A little goes a long way.

Step three

Massage

Work it in with your fingertips for one to two minutes. Leave in. Style as usual.

What our customers say

Questions, answered.

What is the peptide serum?

A lightweight, water-based leave-in for the scalp. Five lab-made signal peptides (the Fivefold Complex) and six botanicals in a formula that absorbs in seconds and leaves nothing behind. Applied by dropper directly to the scalp, once a day. Works on its own or alongside prescription topicals. No silicones, no heavy oils, no added fragrance.

1 fl oz / 30 ml, a one-month supply. Made in the USA.

What are the benefits of using this serum?

Manefold is built to do one job well: support fuller-looking hair at the root.

  • Supports natural hair growth – five signal peptides target the follicle, where hair begins
  • Fuller-looking hair – visible fullness with 3–6 months of daily use
  • Thicker, stronger-looking strands – arginine and wheat germ support strand strength and shine
  • Balanced, nourished scalp – saw palmetto and scutellaria root help maintain a healthy scalp environment
  • Fresh, clean feel – rosemary and eucalyptus leave the scalp refreshed, not greasy
  • Lightweight leave-in – absorbs in seconds, no rinsing, no residue, style as usual
  • Works with Rx – sits alongside minoxidil and other prescription topicals
  • Sixty seconds a day – a habit you'll keep, which is what makes it work

The full INCI list is under “Full ingredient list” above.

When should I apply the peptide serum?

Once a day, on a dry or towel-dried scalp. After a shower works best: cleanse, towel-dry, then apply. Part your hair where you want more fullness (crown, hairline, temples), apply a few drops directly to the scalp, massage with your fingertips for one to two minutes, leave in and style as usual.

Morning or night both work. Pick one and keep it.

Can I use the serum with Rx topicals like minoxidil?

Yes. Manefold is designed to complement prescription treatments, and many customers pair it with minoxidil. Apply your prescription first, let it absorb fully, then apply the serum.

If you're on any prescription treatment, check with your doctor or dermatologist before combining.

How long until I see results?

Hair grows on a slow cycle, so give it time. Your scalp will feel refreshed from day one. Most people notice their hair looking and feeling healthier within 8–12 weeks of daily use, and fuller-looking hair with 3–6 months.

Consistency is the whole game, which is why we built it to take sixty seconds. Every order is covered by our 30-day money-back guarantee.

What products does the serum pair best with?

The serum is the outside half of the ritual. Pair it with the Hair, Skin & Nails Gummies (6,000 mcg biotin, collagen, zinc and B vitamins) or the Collagen Peptides (20 g per scoop, unflavored) to support hair from within.

For the full ritual, run all three: serum at the scalp, gummies or collagen with breakfast. Both are 20% off when added with the serum.

Try it for 30 days. Love how your hair looks, or send it back.
