Is Scalp Activating Lotion suitable for thinning hair and hair loss?
Yes. It is designed as daily cosmetic scalp care for women and men who notice thinning, finer hair or increased shedding. It supports a healthy scalp environment – an important basis for healthy hair growth – without adding hold.
If hair loss is sudden, patchy or very heavy, please see a doctor to clarify the cause.
What is Kopexil and how will it help me?
What it is. Kopexil (INCI: Diaminopyrimidine Oxide) is a cosmetic active used in scalp-care products for thinning hair.
R&DETAIL uses 1.5% in a water-based formula, combined with Panthenol, Zinc PCA and Zinc Gluconate to care for the scalp. The formula is alcohol-, silicone- and fragrance-free.
How it is meant to help. Hair grows from the scalp, so scalp condition matters. The lotion activates the scalp and supports the conditions for healthy hair growth, so thinning or fine hair can look and feel fuller over time.
How long until I notice a difference?
Hair only grows slowly – about 1 cm a month, so visible changes take time. Plan for several months of regular daily use.
One bottle lasts about 3 months, and our before and after photos show results after 4–6 months.
Some users notice less hair falling out within the first weeks. Individual results vary.
Is it for men and women?
Yes. Scalp Activating Lotion is for men and women with thinning or increased hair shedding.
The lotion is alcohol-free and fragrance-free.
If you notice sudden, patchy or very heavy hair loss, or your scalp is red, painful or scaly, please see a doctor first to find the cause, before you use the Scalp Activating Lotion.
Please check with your doctor if you have had a recent hair transplant.
How to use
Twist the nozzle open and apply the lotion directly from the bottle onto the scalp.
The formula is lightly thickened with a guar-based ingredient, so it stays where applied instead of running. Distribute over the desired areas and massage gently with your fingertips.
Use on a dry or freshly washed scalp. Do not rinse.
Only a light wetting of the scalp is needed – approximately 1 ml per day.
Depending on the amount used, one bottle is designed to last for around 3 months.
Should I use the Lotion with Skin Caring Shampoo and Hair & Scalp Treatment?
You can use the lotion on its own, but we recommend the R&DETAIL care system. Skin Caring Shampoo gently cleanses hair and scalp – the ideal base for your caring routine.
The Hair & Scalp Treatment adds extra nourishment and is especially helpful for longer, dry, coarse or chemically treated hair, or a dry, itchy, greasy or dandruff-prone scalp.
With short hair you can start with Shampoo and Lotion and add the Treatment if your hair or scalp needs it.
The Scalp Activation Trio is designed to work together and combines all three benefits.
Can I combine it with Minoxidil or other hair-loss treatments?
Scalp Activating Lotion is a cosmetic care product and does not replace prescribed therapy. If you use Minoxidil or another hair-loss treatment, are under medical care or have had a recent hair transplant, please ask your doctor before combining products.
Is it alcohol free? Will it burn or tingle?
Yes, it is water-based and alcohol free. Many classic scalp-activation formulas use an alcohol base, which can dry out the scalp or cause burning on sensitive skin.
R&DETAIL is made for regular daily leave-on use, so no burning or noticeable tingling is expected.
Will it make my hair greasy or change my styling?
The formula is water-based and has no hold or styling effect. It will not weigh the hair down or make it look greasy. Apply it to the scalp, leave it in and style your hair as usual. This makes it especially suitable for longer hair or hair that is not washed daily. For light root hold and volume, choose Scalp Activating Lotion Hold.
