The Guarantee

If your hair doesn't change, we will.

Use the Hair Growth Kit for 150 days, document along the way, and if you don't see results, we'll refund your kit and serums in full.

What to Expect

Real results take time.
Here's the rough roadmap.

Everyone's hair is different, but most of our customers start noticing changes on this kind of timeline. Photograph yourself monthly — you'll see it before the mirror does.

30days

Hair starts to feel different

Softer texture and a healthier-looking scalp. The first subtle wins.

60days

Baby hairs appear

Fine new growth becomes visible along the hairline and any treated areas.

90days

Visible density

Fuller-looking hair you can see in the mirror — and in your monthly photos.

Track Your Progress

Take a photo
every month.

Progress is hard to spot day to day. Monthly photos are the easiest way to see how far you've come — and they're how we'll verify your results if you ever need to claim the guarantee.

  • Use the same lighting, angle, and distance every month.
  • Capture both the full head and close-ups of the areas you're treating.
  • Save them in order — month 1, 2, 3, and so on.
  • Feel free to share them with us as you go. We love seeing them.

For best results

A simple routine,
followed consistently.

Two products, one daily habit. That's all we ask of you for 150 days.

01 — In the shower

Wash with shampoo & conditioner.

Rinse thoroughly. Product left in the scalp can cause itching, so take an extra moment to rinse everything out.

Frequency1–3× per week
02 — After the shower

Apply the Growth Serum.

Apply daily to the areas you want to treat. One bottle lasts roughly a month with daily use, so you'll want three serums to cover the 150 days.

FrequencyOnce daily
How to qualify

Three steps to
claim the guarantee.

Built to be simple. Built to be honest. Follow these three steps and you're covered.

01
Use the kit

Use the Hair Growth Kit for at least 150 days.

Make sure every product in the kit gets used — that's how the formula does its work. Pair it with three Growth Serums for the full course (about one per month).
02
Document carefully

Photograph your hair and scalp each month.

Take both wide shots and close-ups of the areas you're treating. Keep them in chronological order so we can review your progress at a glance.
Tip: Same spot, same lighting, same time of day. Consistency is everything.
03
Reach out

Don't see the results you hoped for? Email us.

Send your photos and order numbers to hello@underyourskin.se and we'll get back to you. We read every single one.

What's Covered

One full course,
fully guaranteed.

The guarantee covers one Hair Growth Kit and one Growth Serum kit (three serums) — enough to see you through the full 150-day program.

  • Hair Growth Kit
    Shampoo, conditioner, and all the essentials
    × 1 kit
  • Growth Serum Kit
    Three serums — one per month of daily use
    × 3 serums

The fine print, kept short.

To qualify, the Hair Growth Kit must be used for the full 150 days, with all products in the kit actually used. We recommend running both the Hair Growth Kit and a Growth Serum Kit (3× serum) over those 150 days for the best chance of results.

If you choose to keep using the products past day 150, those reorders aren't covered by the guarantee and aren't refundable. The guarantee applies to your first kit and first serum kit only.

Questions before you start? Email us — we'll walk you through it.

Ready when you are

Your 150 days start today.

Grab the Hair Growth Kit and three serums, take your first photo, and we'll see you on the other side.
