A note from our founder
I watched my own hair thin for years and hated that helpless feeling. Nothing worked until I fixed my scalp first. I made ISEUL so you don't have to go through all the trial and error I did. Give me a quick minute and I'll show you how.

We show every review, good and bad. Nothing is hidden.
Fine product but the tingle is strong if your scalp is sensitive. I dropped to once a day and it was much better.
Good. Bottle lasts about a month with twice-daily use, so the 3-pack is the one to get.
Postpartum shedding was brutal. This is the only thing that made a visible difference. Cooling feeling is lovely.
The brush is the whole thing for me. No drips down my face, no wet pillow. It takes about twenty seconds.
Three months in and the shedding has basically stopped. My scalp stopped itching in the first week, which is what convinced me to keep going.
Works, but be patient. I saw nothing for six weeks and almost gave up. Month three is when people started asking what I'd changed.
No reviews match that filter.
Before you ask
Pick a topic to jump straight to your answer.
It's a scalp serum for hair loss, thinning, and itchy scalps. It calms your scalp and makes a healthier home for your hair to grow.
After you shampoo, twist the brush open, glide it over your damp scalp, then twist it shut and massage in. Do this morning and night.
No. The built-in brush puts the serum right on your scalp, so nothing runs down your forehead or face.
Everyone is different. Most people feel a calmer scalp in the first week. Fuller-looking hair takes longer, so give it about 3 months of daily use.
Think of it as a daily routine, not a quick fix. Use it every day for at least 3 months to give your hair a fair chance.
All of them. Straight, wavy, curly, coily, fine, or thick. It works on your scalp, not your hair strands, so hair type doesn't matter.
Yes. It's fragrance-free, paraben-free, and made to be gentle. If your scalp is very sensitive, start once a day.
No. It's fragrance-free. You'll feel a light cooling tingle from the menthol, but there's no perfume smell.
