F.A.Q

help

How long until I see a difference?

Many people notice a difference in how their hair feels and looks within a few weeks of regular use. Everyone’s hair and scalp are different, so give it at least [4-8 weeks] of consistent use before judging.

help

What’s actually in it?

The formulas use well-known scalp-care ingredients such as niacinamide, dexpanthenol and salicylic acid. The full ingredient list is on each product page, so you can check it against your own sensitivities.

help

Will it stop my hair from falling out?

Dr. Groot is scalp care, not a medical treatment. It’s designed to help hair look thicker and fuller, and it doesn’t change your genetics or hormones.

If you’re losing hair suddenly or heavily, we recommend seeing a doctor.

help

Is it safe for sensitive scalps?

It’s dermatologically tested and made for all scalp types. We recommend a small patch test the first time, and stopping use if you feel irritation.

help

Does it contain hormones?

No. These are topical scalp-care products. They are not pills and they don’t contain hormones.

help

Does it work on curly, textured, fine or colored hair?

Yes. It targets the scalp, so it works with most hair types and wash routines, including curly and textured hair.

    I'm so happy! Here's a photo of all the new hair that's growing in. I hope you get the same results! I can't wait for the new hair to grow long enough so I can cut off the remaining tousled ends.

    Expensive but effective. This product is very special. I have only used it one time since it's delivery and I can already see and feel differences in my hair and scalp. Can't wait to do further shampooing
