  • "I love it, it keeps my hair soft and hydrated 10 out of 10"

  • "Great products, I use them every morning"

  • "I love Smooth Labs, they make the best products."

  • "The only products that work on my hair"

  • "Regular shampoos destroy my hair, this one is different"

  • "Nothing to say, the products are very high quality"

Is this product made for me?

If regular shampoo leaves your hair dry, flat or full of flakes, this is the one.

  • All hair types

  • Dry, brittle or frizzy hair

  • Dandruff or an itchy scalp

Finish with Conditioner and your hair will feel completely different.

How is it different from other shampoos?

Most shampoos strip your hair clean, then leave it feeling like straw.

We took out the sulfates, the parabens, the silicones and the drying alcohol. Then we packed it with onion seed oil, black seed oil, argan oil and caffeine. It still foams. It still cleans. It just doesn't wreck your hair doing it.

  • Clean, not stripped. Fresh scalp, soft hair.

  • Fights dandruff. Your scalp finally calms down.

  • Stronger hair. Less brittle, less breakage.

  • Real volume. No silicones weighing your hair down.

my hair doesn't feel like straw anymore

I wash my hair basically every day because of the gym and my old shampoo made it feel like straw by the end of the week. switched to this a few weeks ago and it's soft again, even washing that often. didn't think a shampoo could make that much difference tbh

can wear black tees again

Had flakes on my shoulders every time I wore a black t-shirt, super embarrassing at work. The anti dandruff ones from the supermarket made my scalp tight and itchy so it came back anyway. After a couple of weeks with this my scalp finally calmed down. Wearing black again

fine hair, finally some volume

I have thin straight hair and most shampoos leave it flat and kind of greasy by lunch. Found out that's the silicones. This one has none and my hair actually has volume now, even before I put anything in it

curly and finally not frizzy

My hair is curly and dry and most shampoos turn it into a frizz ball. This cleans without drying it out, my curls actually look like curls after. My barber noticed before I said anything

the combo with the conditioner

Got the Ultimate Shampoo and the Ultimate Conditioner together. Honestly didn't think I needed both, I have short hair lol. But together it's a different level, my hair is still soft the next day

doesn't smell like onion lol

saw onion seed oil on the bottle and nearly didn't buy it because I thought I'd smell like a kebab shop. it doesn't smell like onion at all, it's a light fresh smell, nothing strong. and my hair has more volume too

28€ made me hesitate

ok 28 euros for a shampoo made me hesitate. but it's 480ml with a pump and one or two pumps is enough. I've been using it since september and I'm not even at half. my old 250ml bottle from the supermarket was gone in 3 weeks

my scalp calmed down after football

I sweat a lot at football training and my scalp used to itch like crazy, especially after the cheap stuff in the changing room. Read that this has black seed oil which is supposed to calm the scalp, no idea about the science but it itches way less now

bleached hair, way less breakage

I bleached my hair this summer (bad idea) and it got super brittle, little bits snapping every time I brushed it. This with the onion and argan oil is the first thing that made it feel strong again. Way fewer broken bits in the brush now

natural and it actually cleans
