So, you'll likely first have heard of salicylic acid as a skincare ingredient, and if you've found your way here because you've seen it's in shampoos too. Well, we're here to tell you everything you need to know about the wonder ingredient, as well as to recommend some of the best buys across all price points and hair types. It's heaven-sent for dry, flaky irritated scalps, but also is a dream for oily scalps too. Not to mention it's a win for smoothing and hydrating. A true all-rounder. Now that we've secured your attention, let us elaborate.

Is salicylic acid shampoo good for hair?

Salicylic acid is a beta-hydroxy acid (BHA), explained clinical trichologist Kate Holden; "which means that it’s an oil-soluble exfoliant that can penetrate hair follicles." And why is that such good news for our headtops? "This makes it particularly effective for oily or flaky scalps, loosening and removing dead skin cells and tackling build-up of sebum and grime," she continued. Even if you don’t struggle with a flaky scalp, according to Kate it can improve the efficacy of the rest of your hair care; "the exfoliating properties of salicylic acid can help improve the absorption of conditioning or moisturising ingredients. So if your shampoo or conditioner doesn’t seem as effective as it used to, or your hair feels frizzy or dry, incorporating salicylic acid can help to promote healthier hair."

If you aren't sold yet, among its other strengths are its anti-inflammatory effect, and that it can help to reduce sebum production, making your scalp less greasy over time. Still have questions? We got Kate to answer the most common ones.

Who are salicylic acid shampoos suitable for?

"Anyone who struggles with an oily or flaky scalp can benefit from a salicylic acid shampoo. We also use salicylic acid to help in scalp conditions such as seborrhoeic dermatitis or psoriasis. However, dry scalps might find salicylic acid stripping."

Is there a % needed to be effective?

"The concentration of salicylic acid in therapeutic shampoos is usually between 0.5% – 2%, with higher percentages being more exfoliating. The lower down salicylic acid is listed on the packaging, the lower the percentage is in the product."

Is there a difference between a salicylic acid shampoo, and a shampoo with salicylic acid?

"No. The change in emphasis can give you a clue as to what the main active ingredient is, so a salicylic acid shampoo will likely focus on salicylic acid as the primary active, but you really need to read the label to know for sure."
