    How to use the Hair Growth Kit?


    Hair Growth Shampoo

    Step into the shower and when your hair is wet - apply Hair Growth Shampoo all over the hair and scalp, massage it into the scalp and rinse. This step doesn’t have to be used every day.


    Hair Growth Conditioner

    Once your hair is cleansed, apply conditioner from the center of the hair down to the bottom to soften and moisturize the hair. Leave on for 1-2 minutes and then rinse off.


    Hair Growth Activating Serum

    You can use Activating Serum on a dry or wet scalp. You use the pipette to drip product all over the scalp - a half-full or full pipette is usually enough to cover your scalp. Once it has been applied to the scalp, massage the product into the entire scalp with your hands. Do not rinse.

    Frequently asked questions

    Let's be honest, this is a miracle product, but it takes time to grow new long hairs. Here are some common questions:

    Results About the products

    How fast does it decrease hair loss?

    If you don’t have a specific diagnose (then it can vary), you will pratically see the results immediately, already the same week. Make sure you brush your hair before you start using our products and then afterward, to see how much hair is left on the brush. If we are going to be careful, you can also weigh the hair you normally lose before you start and after you have used the products for a week. You will then notice that you lose up to 89% less hair in the coming weeks, but it needs to take 90 days for the best results.

    How quickly can I notice that I get more volume in my hair?

    As you lose less hair, after a few months (3-5) you will see that you start to get more volume in your hair. In external studies, 95% of people experienced that the hair feels healthier and stronger than ever. But of course, it also depends on how much hair you had before you started using the products. If you had very thin hair, it may take a while before you start seeing visible results.

    How quickly do I notice that I am getting new hair?

    It takes a long time for a new hair to grow out, but after 150 days you will notice that new hairs are being formed on the scalp. After that, your hair normally grows on average 1.15-1.45 cm per month. If you don’t see a noticeable difference after 150 days, we have a Money-Back guarantee that we refer to. Of course, you can continue to use the products and try for longer than 150 days, especially if you notice that you reduced hair loss and started to get more volume in your hair.

    How does it work?

    With the active ingredient Capilia Longa PPF which is a concentrated secretion of totipotent cells from the root of Turmeric that is rich in signal peptides, specially designed to create an optimal microenvironment for reactivation of hair growth. The serum we’ve created reactivates an epigenetic restoration of hair follicle regeneration and moisturizes it with nutrients specially developed for hair. If you want to inform yourself further, it is good to contact us at and we will send you a longer presentation about the product and how it works biologically.

    How long does the Hair Growth Kit last?

    Depending on how thick your hair is, it can vary. The shampoo & conditioner should last for about 50-90 days and the serum is enough for about 35 applications (about 35 days).

    Can I buy the serum separately if it runs out?

    Yes, you can. The serum is available to buy separately and it costs SEK 399.

    Do I need to continue using the kit even when I get results, or should I switch to the Detox kit?

    Continue to use the products until you achieve the desired result, when you achieve your desired result, you can switch to using only serum 2-3 times a week.

    Does the serum work to grow beard or hair in places other than the head?

    Yes - you can also apply the serum to the beard or other places where you want increased hair growth.

    With 100% confidence in the result

    We are confident in the knowledge that our Hair Growth Kit works, so confident that we offer you a 150-day guarantee if you are not satisfied with the result.

    Ana Strehaljuk (Stockholm, SE)
    Hair Growth Kit

    Jag har använt Hair Growth Kitet sedan maj 2023 hade precis bestämt mig för att kapa av mitt långa hår till en riktigt kort page 💇🏻‍♀️.

    Mitt hår har alltid varit tjockt och fylligt men har upplevts ganska livlöst och matt. Mitt hår har för det första vuxit som ogräs (trots att jag har klippt mig emellan), nu har mitt hår glans och är fullt av liv och jag får så mycket komplimanger för mitt fina hår.

    Första bilden med kort hår är från förra sommaren 2023 och den andra bilden med keps och långt hår är från påsklovet 2024 när vi gick ett bakslag med snöfall igen.

    Rekommenderas varmt ☀️ både till alla här men också till alla kollegor, familj och vänner som nu också har blivit användare av Under Your Skin Produkter 🫶🏼

    Daniela (Stockholm, SE)
    Bästa hårprodukterna

    Aldrig har min hårbotten mått så bra!! Jag har så länge jag kan minnas haft kli och sår samt fjällande hårbotten, använder nu både serum, schampo och balsam ifrån UYS och både håret och hårbotten mår jättebra!

    Ester (Gothenburg, SE)
    Rekommenderar ej

    Använde detta i ca en månad och fick en allergisk reaktion med nässelutslag, klåda och mjäll. Behövde såklart sluta direkt med schampot eftersom jag fick stora utslag i hårbotten och nacke, hörde av mig till dem men fick bara svar att jag inte får pengar tillbaka eftersom jag inte användt det i 150 dagar (vilket jag såklart inte kan för fick utslag?!) utan kan få ett annan schampo istället. Vågar inte testa något annat såklart eftersom detta förstörde min hårbotten. Hade önskat pengar tillbaka.

    Maryam (Stockholm, SE)
    Hair growth kit

    Jag har använt detta schampo i ungefär en månad och jag känner att mitt hår blir fylligare och känns friskare men jag tappar fortfarande hår och tycker även att mitt hår blir oljigt lika snabbt (mitt hår är sedan innan oljig) men jag har nu beställt hem en scalp borste för att testa tvätta håret med den och se ifall det blir någon skillnad. Detta har även gjort att jag har kombinerat ett annat schampo med dessa och det kanske även har påverkat resultatet!

    Jill Pettersson

    Jag har använt Hair growth kit och tycker tyvärr att mitt hår har blivit jättetorrt! Jag har självlockigt hår och vet inte om det påverkar. Jag kommer fortsätta att prova då jag var jättenöjd med Detoxprodukterna. Tycker att jag känner en liten skillnad med serumet och kommer som sagt fortsätta för att se om det blir någon mer skillnad.

    Anonym (Örebro, SE)
    Wow, det funkar!

    Det tog närmre 4 månader sen såg jag skillnad. Mitt tunna spretiga bebishår i luggen blev fluffigt och långt. Nästan så jag fått en helt egen lugg. Riktigt glatt överraskad att det gav så bra resultat

    Caroline A
    Efter 4 veckor

    Har använt produkterna i en månad och trodde inte det var någon skillnad förrän jag jämförde bilder före/efter. Har köpt en till flaska med serum och ser fram emot att se vad som hänt om ännu en månad!

    Hair growth Kit

    Har använd produkten nästan i 1 månad, har inte sett så mycket skillnad men ser verkligen framemot. Jag få nog använda produkten ett tag till.
