Meet the ingredient
You've tried rosemary. You've tried castor oil. Meet Usma.
Usma (Isatis tinctoria) is a green botanical that families across Central Asia have worked into the scalp and brows for generations. It's an everyday ritual there, and almost unknown here.
Ours comes from farms near our founder's hometown, the region where the tradition began.
Their hair, months apart
Studied, not just storied
A heritage botanical that science took seriously.
Usma is one of the rare traditional ingredients that modern researchers have examined for its relationship with the scalp and hair follicle.
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.
Kaempferol
Antioxidant flavonoid that helps defend the scalp from daily oxidative stress.
Tryptanthrin
A clarifying botanical compound long valued in Usma's traditional use.
Indigo & Indirubin
Usma's signature blue-green compounds, the ones that first drew researchers to the plant.
Three steps, 2–3 times a week.
Mix
Mix 1–2 tsp with warm water into a smooth paste.
Apply
Apply to scalp and hairline. Leave on 20–30 minutes, or longer if you like.
Rinse
Rinse with water. That's it.
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 feel such a huge difference in my hair & scalp health after using his hair mask. I try to use it every few weeks to freshen my scalp and it does such an amazing job. My roots feel clean and much stronger after each use. After over a month of consistently using this mask, I’ve noticed my hair growing noticeably quickly. Love it!
I love that it’s just one ingredient! Natural
Is the way to go!
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.
Can I rinse the mask off with shampoo? Or just water?
Either works. If you’re short on time, or you’ve used the mask on your hairline before washing your face, plain water rinses it out easily. If you apply it before your shower, shampoo it out as usual for a cleaner finish. The mask works well with your regular shampoo, so there’s no need to worry about any reaction between the two.
Does it make your hair a darker color buy using it 2 or 3 times a week.
No, the mask doesn’t dye or tint your hair. With regular use, brows and hair can look fuller, which can make them appear a little darker, but the color itself stays the same.
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.
