Striking the balance between clean hair and hair that’s easy to style and looks healthy is not always as easy as you’d think. For the most part, for styles to stay put, they’ll need a little helping hand with things like styling creams or texture spray, but these will often contain waxes and silicones to lock out humidity. The thing is, while that’s great for hold, these ingredients will also build up on your hair and scalp as they aren’t absorbed. Product build-up will leave strands looking and feeling lank and scalps flaky—not cute. To remedy this, you need one of the best shampoos on the market. Most importantly, a clarifying shampoo.

These shampoos are important for all hair types for multiple reasons. "Using a clarifying shampoo is especially effective before you put on a deep conditioning treatment,” says Samantha Cusick, founder of Samantha Cusick London. "This is because the shampoo removes all the nasty build-up that gets caught up in the hair and means hair treatments can get into the hair more effectively.”

We've been busy testing out some of the best clarifying shampoos.

What Is A Clarifying Shampoo?

"Shampoos by their very nature are clarifying, containing a detergent/surfactant such as a sulphate to cleanse away sweat, sebum, dirt and pollution," explains Anabel Kingsley, brand president and consultant trichologist at Philip Kingsley. "If they weren’t clarifying, the formula wouldn’t be fit for purpose. So, all shampoos should be clarifying; however, people often refer to clarifying shampoos by means of giving a 'deeper' cleanse than a regular shampoo."

Yep, these shampoos are for when your hair is in need of a really good wash. If you have a lot of product build-up, then this is the formula to reach for. Oh, and don't forget to follow up with one of the best conditioners on the market.

How Often Should You Use A Clarifying Shampoo?

A good clarifying shampoo will do more for your hair and scalp than any other shampoo type, but should be used in tandem with other, less potent formulas to keep hair healthy.

"I would recommend a clarifying shampoo/treatment at least once a week to support hair health," advises Kingsley.

Is A Clarifying Shampoo Good For Your Hair?

In the past, finding the best clarifying shampoo has been tricky. Formulas would often contain such a high concentration of detergent that while it was effectively cleaning your hair and scalp, they would also strip colour and all natural oils from the hair, leaving it squeaky clean and often very dry. Now, clarifying shampoo formulas have evolved and manage to still leave hair feeling soft and easy to manage post-wash.

Here are the ones that give all the good hair days...
