What's Inside Usma
One ingredient. A whole spectrum of plant actives.
Usma isn't simple — it's concentrated. Inside that single leaf is a family of plant compounds researchers have identified, each supporting a healthier scalp and stronger-looking hair.
Caffeic Acid
Soothes and calms the scalp, supporting a healthier foundation for hair to grow from.
Gallic Acid
A potent antioxidant that helps protect hair and scalp, supporting strength and resilience.
Indigo & Indirubin
Usma's signature blue-green compounds — the ones that first drew modern researchers to the plant.

Kaempferol
Antioxidant flavonoid that helps defend the scalp from the daily oxidative stress that tires follicles.

A clarifying botanical compound long valued in Usma's traditional use.

A centuries-old ritual, made for modern hair.
Long before serums and supplements, women across Central Asia had one answer for thinning hair and weak ends — a single green botanical, worked fresh into the scalp.
We kept it pure and made it effortless. One ingredient, mixed fresh by you, used the way it was always meant to be.
Having only used it twice so far, I cannot yet comment on the efficacy, but if I can gauge by way the oil works, I'm sure it will be really good! Super easy to use, you just mix a little bit with water in the tiny bowl, and I used the end of the spoon to smear it onto my scalp! It's quick to apply, and washes out thoroughly. I have no doubt that it will improve my perimenopausal scalp over time and consistent use.
I love the Usma hair mask. My scalp feels nourished and healthy. And even though I used it more targeted towards my scalp, it left my hair feeling healthy and with lots of volume. A little goes a long way and I found that I didn't need a lot in order to cover my whole scalp.
I love how this smell and its very special product. I also think its much easier to use that i thought because you can clean it with just water very easily.
FAQs
How often should I use the mask, and how long until I see results?
It depends on frequency, but with reasonable, regular use here's a general timeline: in the first few uses, you'll notice a cleaner, less sensitive, healthier-feeling scalp. Around month 1, hair shedding starts to slow down. By month 2, hair tends to grow a bit faster. Around month 3, you'll start to notice new baby hairs coming in. (Use 2–3 times per week as a baseline — daily is fine too if you want faster results, just deep-cleanse once a week to avoid buildup, since it's a gentle, clean ingredient that won't make hair oily or dry.)
What's actually in it?
One ingredient: 100% pure Usma powder (Isatis tinctoria). No fillers, no fragrance, no synthetic additives — just the plant.
s it safe for sensitive or fragrance-sensitive scalps?
Yes, it's generally safe and gentle. That said, Usma is a grass, so if you have known allergies to grasses or plants (similar to fruit/vegetable allergies), there's a chance of a reaction — patch test first if you're very sensitive. If you don't have that kind of sensitivity, you shouldn't need to worry.
How do I use it?
Mix 1–2 tsp with warm water into a smooth paste, apply to scalp and hairline, leave on at least 30 minutes, then rinse thoroughly.
Will this work on color-treated or chemically processed hair?
Since it's a single natural ingredient with no chemical additives, it's generally gentle enough for treated hair — but if you've had recent chemical services, patch-test first or check with your stylist.
How long does one bottle last?
Each bottle is 1.6 fl oz / 50 ml. Since you only need 1–2 tsp per use, a bottle typically lasts several weeks at the recommended 2–3x/week frequency.
Is it cruelty-free?
Yes — vegan, cruelty-free, and handcrafted in small batches in NYC.
Can I use it on my eyebrows too?
The Hairline & Scalp Growth Mask is formulated for scalp and hairline use; Nãzuk has a separate eyebrow-specific mask for brows.
