Should You Shampoo Twice?

By Hailey Ward


Shampooing twice, often called double cleansing, has become a popular hair care practice. The first wash removes dirt, oil and product build-up, while the second ensures a thorough cleanse. 

Advocates believe it leads to healthier, shinier hair and a cleaner scalp. But should you shampoo twice? Is there any real benefit? Let’s take a look. 


Exploring the pros and cons

As with a lot of self-care, there are benefits and potential drawbacks of double cleansing your hair. 

Benefits of shampooing twice

  • Thorough cleansing

Double shampooing can remove dirt, oil and other impurities, leaving hair feeling renewed and looking shinier. 

  • Removes product build-up

Shampooing twice can help to clear residue from styling products for fresher hair.

  •  Better scalp health

Double cleansing can give you a cleaner, healthier scalp, free of product build-up. 

  • Better product penetration

Once all of your impurities have been removed with the first cleanse, a second can allow any active ingredients in your shampoo to work more effectively.


Cons of shampooing twice

  • Strips natural oils

Washing your hair twice with shampoo may remove too many of your skin’s natural essential oils, leading to dryness.

  • Causes dry hair

Aside from making your scalp feel dry, double cleansing can make your hair itself feel dry and brittle. The oil from your scalp is what keeps hair nice and moisturised. If your scalp is dry, your hair will be too.

  • Barrier damage

Contrary to the popular saying, squeaky clean isn’t all it’s cracked up to be – at least not for us. Just like the skin on your body, it’s important that you don’t overwash your scalp. Doing so may disrupt the natural balance of the skin on your scalp, causing irritation.


Understanding hair and scalp health

Keeping a healthy balance of oils on the scalp and hair is important for general hair health. This natural sebum is what protects and nourishes the hair, preventing dryness and breakage. 

It’s essentially a miracle oil for your hair – your body knows exactly how much your hair needs to keep it healthy. The pH level of your natural oils flattens your hair cuticles, keeping it smooth and silky. It prevents your hair from losing water, every day after you wash it. So, the more you wash your hair, the more oil you produce. This is why overwashing your hair can lead to greasiness, and the cycle continues. 

The key is gentle cleansing, and not too much of it. Harsh shampoos can strip these oils from the hair and scalp, leading to dryness and irritation. 

By choosing shampoos formulated with nourishing, moisturising ingredients like argan oil, panthenol and aloe vera, you can help maintain this balance. These ingredients cleanse, hydrate and soothe the scalp, promoting healthy hair growth.
