Benefits

A liquid serum for the scalp surface, with no scrub particles at all.

A gentle acid exfoliates the scalp surface in 3 to 5 minutes, before you wash.

Sodium hyaluronate helps hydrate while the serum works.

Vegan and made without added fragrance. Check the full ingredients if your scalp is sensitive.
Why we made it
For the weeks your scalp feels coated and a gritty scrub doesn't appeal. A few quiet minutes, just before you wash.
Lactic acid exfoliates the scalp surface in a light serum with sodium hyaluronate for hydration. Leave it on for 3 to 5 minutes, then rinse and shampoo. Prefer a physical scrub? Choose the scalp scrub instead. Use one per wash.
The ritual
Before you wash, on a dry scalp, part your hair into a few sections.
Apply the serum along each part and massage it in gently with your fingertips.
Leave it for 3 to 5 minutes. If it feels uncomfortable, rinse immediately and stop using it.
Rinse thoroughly, then wash as usual with the gloss shampoo.
Start once a week. If your scalp feels comfortable after a few weeks, twice a week is fine.
The formula
A gentle exfoliating acid that helps loosen product buildup, so your shampoo can wash it away.
A form of hyaluronic acid that holds on to water, for lightweight hydration.

Nettle leaf extract from organic farming, part of a short and simple formula.
A little more clarity
Can I exfoliate my scalp without gritty particles?
Do I need both a scalp serum and a scrub?
Choose the texture you prefer: this serum exfoliates with lactic acid and has no grit. The scrub uses clay and cherry shell particles. Both rinse out before shampoo; choose one for a wash, rather than using both together.
Start once a week. If your scalp stays comfortable after a few weeks, you can use it twice a week. If your usual shampoo already leaves your scalp comfortable and clean, an extra exfoliating step may not be needed.
Before washing, part dry hair and apply along the scalp. Massage gently, leave for 3–5 minutes, then rinse and shampoo as usual. It is a pre-wash step, not a leave-in serum or a replacement for shampoo.
Tingling is not a sign you need to feel for it to work. If it stings, burns, itches or feels uncomfortable, rinse it off and stop using it. Avoid applying it to an already irritated scalp.
No. This is a cosmetic exfoliating serum, not a treatment for dandruff or a scalp condition. If flaking, redness or itching keeps returning, ask a dermatologist for advice.
We have not established color-treatment compatibility. Follow your colorist’s aftercare advice, especially if your scalp feels sensitive after a treatment.
It is a light, water-based serum without exfoliating particles. Rinse it out fully, then shampoo; it is not designed to stay in your hair.
It has no added fragrance and is vegan, with no keratin. It is the only PALIM product without added fragrance. The full ingredient list is above.
