The best scalp cleansers to buy in 2023

Give your scalp a deep clean with the best scalp cleansers for super-shiny, healthy hair

You probably already know that healthy hair starts with a good cleansing and conditioning routine, with shampoo and conditioner products suitable for your hair type. However, for a deep clean that removes build-up of dirt and dead skin from the hair, you’ll need a specialist scalp cleanser.

A build-up of sebum, skin flakes and styling products on the scalp can cause irritation, while also blocking hair follicles. Scalp cleansers usually combine an exfoliating scrub with gentle cleansing ingredients suitable for the delicate skin on the scalp; these lift away any build-up and cleanse the scalp of oils and environmental residue. Like double-cleansing the skin on your face, washing your scalp allows hair to grow freely from the root, and enables nutrients to reach your scalp and hair follicles more easily.

Scalp cleansers are particularly good for oily scalps, but the right combination of ingredients can also benefit all hair and skin types, including dry and sensitive scalps. We’ve tested a range of scalp cleansers and picked our favourites for all hair types below.

How to choose the best scalp cleanser for you

What is build-up?

Build-up is the name given to any residue that remains on the scalp and root of the hair after shampooing and rinsing. It can be formed of many things: oil and sebum produced by the scalp; flakes of dead skin that stick to oily residue; dirt and environmental pollution; styling products, and even leftover shampoo. All of this can block hair follicles and slow hair growth, so cleansing the scalp can help your hair grow to its natural maximum.

Environmental and product build-up can also cause irritation. Giving the delicate skin of the scalp a gentle cleanse can help reduce itchiness, flaking and inflammation.

How does a scalp cleanser work?

Scalp cleansers combine gentle cleaning ingredients, similar to those found in shampoo, with some form of exfoliator. This will take the form of a physical scrub, such as salt or sugar granules or fine-ground nuts or grains; or a chemical scrub, with alpha hydroxy acids (AHAs) or beta hydroxy acids (BHAs) to dissolve dead skin cells. In either case, the scrub works into the scalp to gently work away and lift off build-up, which is then rinsed away.

Most scalp cleansers can be integrated simply into your usual routine. Part your wet hair and apply cleanser close to the roots and scalp, then massage in as directed before rinsing and following with your usual shampoo and conditioner. A scalp cleanser can be used around once a week, depending on the issue you’re trying to treat. Like facial scrubs, it’s best not to exfoliate the scalp too often since this may cause irritation. Avoid using a scalp scrub on damaged or broken skin.

How else can I keep my scalp healthy?

While cleansing is an important part of a scalp-care routine, overwashing can strip the hair of its natural oils and conversely encourage excess production of sebum. As such, if your scalp is itchy and irritated, try washing less often and with more gentle products to maintain its own natural balance. Those with a sensitive scalp may find that avoiding products containing sulfates and parabens improves the overall condition of the scalp.

Massaging the scalp gently with the fingertips between washes can also help loosen excess skin flakes and increase circulation to the head and scalp. This allows the blood to bring nutrients to the area, promoting strong and healthy hair growth. A head and scalp massage is also a wonderful way to relax before bed. Finally, eating a healthy, balanced diet will ensure that your hair and scalp are fed and nourished from the inside out.

How we test scalp cleansers

At Expert Reviews, we know that the best way to test a product is to use it ourselves. We test all the scalp cleansers we review by using them as directed. If a product is recommended for a particular hair type, where possible, we will test on that type to provide an accurate assessment.

We start by reviewing the main cleansing ingredients; whether the product uses a physical or a gentle chemical exfoliant, thereafter evaluating the effects of the cleanser on the feel of the scalp following one wash and after multiple uses. As well as noting the effects of the cleanser on the scalp and hair, we assess how the product feels in use and any grittiness or tingling that we might experience in use. We also consider how easy it is to rinse out a formula. We note how much product is required for a single application, its scent, and make an evaluation of how easy and pleasant a product is to use overall.
