Product Description

Fast-absorbing and skincare-inspired, Overnight Scalp Barrier Serum is designed to support and strengthen the scalp's natural skin barrier function. Working with your skin's circadian rhythm while you sleep, it helps to create a healthy, balanced scalp environment, support long-term scalp health and minimise the onset of scalp issues.

WHY USE IT:
The scalp is essentially an extension of the skin on your face, and, as with the skin on the face, has a skin barrier to help protect and keep it healthy. Yet this protective barrier is easily disrupted through over-exfoliation, environmental pollution, dry climates, UV exposure, stress, harsh products and ageing, and when this happens, scalp issues (like dryness or dandruff) can take hold. The soothing formulation is powered by a pioneering Triple Balancing Action, which fortifies scalp health in three ways: improves hydration, regulates oil production and balances microflora.

WHO IS IT FOR?
Suitable for all scalps and hair textures. The formula will help to maintain scalp health with no concerns, as well as benefiting those who experience mild, intermittent flaky patches, excessive oil, dryness and mild irritation, due to its barrier strengthening and balancing qualities.

Directions

Apply in the evening, the day before you wash your hair.
Fill the pipette by pressing down on the top of the dropper. To dispense, gently press again.
Apply directly to the scalp in 4-5 sections, using 2-3 drops per section.
Massage gently over your scalp. Expect a soothing sensation. Do not rinse.
Upon waking, wash and style as usual.
HOW OFTEN SHOULD YOU USE IT?
For best results, repeat every evening if you wash your hair daily or the night before hair wash day.

Rated 5 out of 5 by from Great Product It immediately calmed my scalp although when you get to the bottom it’s hard to get the serum out with the pipette. It is now firmly in my scalp treatment regime. A great product!

Rated 5 out of 5 by from I really love this product. I really love this product. My scalp is super sensitive and this serum is making it feel a lot better. I was also pleasantly surprised with the application process, it's less messy than I was expecting and after sleeping with it, my hair doesn't look all that bad, so I'm ok getting some things done (eg groceries or running) before hopping into the shower.

Rated 5 out of 5 by from Absolutely brilliant Philip Kingsley’s Overnight Scalp Serum is absolutely brilliant. From the very first use, my scalp felt calmer and more comfortable by morning. It instantly soothes irritation and really helps reduce itching and dryness without feeling heavy or greasy. What I love most is how lightweight it is, it absorbs quickly and doesn’t leave residue, so it’s easy to use overnight without worrying about product build-up or messy pillows. After regular use, my scalp feels healthier, balanced, and far less irritated. After trying so many products that didn’t work, this serum genuinely stands out. It actually treats the scalp rather than masking the problem. I wouldn’t be without it now and highly recommend it to anyone dealing with scalp issues.

Rated 5 out of 5 by from This is excellent! Have seen a genuine improvement almost overnight! My scalp is usually by the end of wash day, but through using this serum I can feel and see a difference immediately. The application pippet is easy to use and allows for you to put as much as you need and in different areas, meaning the product is spread out over the scalp making it easy to distribute evenly.

Rated 5 out of 5 by from This super serum, like most This super serum, like most PK products, works as described. My hair feels incredibly smooth, and my scalp appears more nourished, all thanks to the Overnight Scalp Barrier Serum.
