Exfoliation for your scalp. No scrubbing required.

You exfoliate your face. You never think to do the same for your scalp and it's skin too, under more strain than most. Dead cells, product residue, oil and sweat build up at the roots, and that buildup is what leaves the scalp flaky and itchy, clogs the follicles, and weighs hair down so it sits flat and lifeless no matter how you style it.

Scrubbing it off with grit is one way, but not the only one. This serum uses Lactic Acid to dissolve the bonds holding that buildup and dead skin in place, so it lifts away on rinsing no abrasion on a scalp that's often already irritated. Sodium Hyaluronate and Glycerin keep it hydrated and comfortable through the process, while Nettle extract helps purify and rebalance. The result is a scalp that feels genuinely clean and reset.

A clearer scalp is simply a better foundation follicles unclogged, roots lifted, hair looking fuller and fresher from the base up. Apply to a dry scalp, leave for a few minutes, rinse and shampoo as normal. Once or twice a week is all it takes. Fragrance-free, so there's nothing to irritate a sensitive scalp.

How to Use

Weekly — Before Shampoo

1

Section dry hair to expose the scalp this goes on the scalp, not the lengths.

2

Apply a few drops at a time across the scalp, focusing on oily or flaky areas.

3

Massage in gently and leave on for 3–5 minutes.

4

Rinse thoroughly, then follow with the Strength & Volume Shampoo as normal.

5

Use once or twice a week no more than that.

Twice a week is the ceiling. This is a chemical exfoliant more often won't clean the scalp faster, it'll just sensitise it. If you also use the Deep Cleanse Scalp Scrub, alternate them across the week rather than using both in one wash.

Questions

How is this different from the Deep Cleanse Scalp Scrub?

The Scrub exfoliates physically, with beads you massage in. This serum exfoliates chemically Lactic Acid dissolves the buildup so it rinses away, with no scrubbing on an irritated scalp. Some men prefer one over the other; if you like both, alternate them across the week.

Will it sting or irritate my scalp?

Lactic acid is the gentlest of the exfoliating acids, and the hyaluronic acid keeps the scalp hydrated through it. A mild tingle can be normal; if your scalp is sensitive, start once a week and build up. It's fragrance-free specifically so there's nothing extra to react to.

Does it help with thinning or flat hair?

It works on the scalp, not the strand. By clearing buildup that clogs follicles and weighs roots down, it creates a cleaner, healthier environment and lifts the roots so hair looks fuller and fresher from the base. Think of it as the groundwork, not a growth treatment.

Do I use it before or after shampoo?

Before. Apply to a dry scalp, leave it 3–5 minutes to work, then rinse and shampoo as usual. The shampoo clears away everything the serum has loosened.

Where does it fit in my routine?

It's a weekly treat step. Use it once or twice a week before your usual wash, alongside the Strength & Volume Shampoo and, if you use it, the Scalp & Hair Strengthening Oil.
