Made with cotton — not keratin. YLO fibers are natural cotton, colour-bonded with mineral pigments. They cling to the hair you already have to add visible fullness, then wash out with shampoo. What you see is what's in the bottle.

Ingredients: natural cotton fibers, iron oxide mineral pigments. For external use only.

You're far from alone. After menopause, about two-thirds of women experience hair thinning. YLO adds visible fullness in seconds, so thinner areas simply look fuller. Source: Cleveland Clinic, 2023.

The Empty-Bottle Promise — 60 days

Try The System for up to 60 days. If you don't love the way your hair looks, tell us — full refund. Keep the applicator, empty or not. That's the whole fine print.

Why it works

Made to disappear in real light. That's the standard.

Cotton microfibers, color-matched to your hair, that rest among your own strands — and disappear into them.

The 30-second application
Applying YLO hair fibers to the part line with the precision applicator

The precision applicator puts fibers on the part line — not all over your bathroom sink. Spray, blend, go.

We put our money where our mouth is.

A note from the founder

I didn't start YLO (say: ee-lo) because I love hair products. I started it because of a hair tie.

Somewhere in my early thirties, my ponytail started feeling smaller in my hand. Two loops became three. I tried the tricks — eyeshadow on the part line, the strategic side-part, standing on the good-light side in photos.

But patience doesn't help you at 6 p.m. before a dinner. So we built the thing I couldn't find: fibers matched like foundation, tested in real light, honest about what they do — cover, blend, wash out — and what they don't.

If The System doesn't make you feel more like yourself, run the applicator empty and take the refund. I mean that literally — it's in the promise.
