Head and Shoulders is one of the most recognisable names in hair care, often praised for its ability to reduce dandruff and soothe the scalp. However, those who colour their hair are sometimes wary of using this popular shampoo due to concerns that it might strip or fade hair dye. The question of whether Head and Shoulders removes hair colour is a common one, especially for anyone trying to preserve the vibrancy of salon-treated or at-home dyed hair.

Understanding How Shampoo Affects Hair Dye

Hair dye, especially permanent dye, works by lifting the cuticle and depositing pigment inside the hair shaft. Once this process is complete, the dye is fairly resistant to rinsing and normal washing. However, how long your colour lasts still depends on the type of dye used, the condition of your hair, and your overall haircare routine. Using harsh shampoos or washing your hair too frequently can cause the dye to fade faster, particularly if your hair is porous or damaged.

Clarifying shampoos are designed to remove product build-up, excess oil, and impurities from the scalp and hair. Head and Shoulders is not technically a clarifying shampoo, but it does contain active ingredients designed to treat dandruff and cleanse deeply. These properties, while beneficial for scalp health, may also make it more effective at removing surface residue, including some colour molecules, especially in the early days after dyeing.

Is Head and Shoulders Safe for Dyed Hair?

Head and Shoulders is not specifically marketed for colour-treated hair, although there are now some formulas that claim to be colour-safe. For people who have recently dyed their hair, particularly with semi-permanent or vibrant fashion colours, using a dandruff shampoo like Head and Shoulders could cause some of that colour to fade more quickly. This is more noticeable with red, blue, or pastel shades, which tend to be more fragile by nature.

However, if you are using permanent hair dye and your colour has already set, the effects are likely to be mild. Any shampoo that contains sulphates, including Head and Shoulders, can cause gradual fading with repeated use, but it is unlikely to remove your colour completely or cause patchiness if your dye has properly bonded with your hair.

How Much Colour Does It Really Remove?

The degree to which Head and Shoulders removes colour varies depending on several factors. If your hair was freshly dyed within the last 48 hours, you are more likely to notice fading if you use a strong cleansing shampoo. If you have had your colour for a few weeks and it is starting to fade naturally, using Head and Shoulders might slightly accelerate this process but will not strip the colour overnight.

Interestingly, some people use Head and Shoulders intentionally to help fade unwanted hair dye. For example, if someone has overdone a dark tone or applied a colour that came out too strong, using a shampoo like Head and Shoulders can help to gently lift excess pigment without turning to harsher bleaching products. This is especially common when people want to transition to a lighter shade or correct a colour mistake.

Tips for Protecting Your Colour

If you want to continue using Head and Shoulders to manage dandruff or scalp issues while maintaining your hair colour, there are a few ways to minimise any fading. First, opt for the colour-safe variant if available. These are typically gentler and include added moisturisers to help support coloured hair. Second, limit how often you wash your hair. Shampooing less frequently helps preserve both natural oils and colour molecules.

You can also use a colour-depositing conditioner or colour-safe mask once a week to refresh your tone. This can counteract the minor fading that may occur and keep your hair looking vibrant. Ensuring your hair is well moisturised also helps maintain the integrity of the cuticle, which in turn helps lock in colour for longer.

Scalp Care Versus Colour Care

Balancing scalp health with colour maintenance can sometimes be tricky. If you have dandruff or an itchy scalp, treating those issues should come first, even if it means your hair colour fades slightly faster. Inflammation, flakiness, and discomfort can all affect hair growth and confidence, so it is important not to ignore your scalp in favour of colour longevity.

Once your scalp is in better condition, you can reduce your use of medicated shampoo and return to a colour-safe routine. It is always worth consulting with a haircare professional if you are unsure which products are best for your hair type and scalp needs.

How Collagen Supports Hair Quality

While shampoo is one part of the external care routine, supporting your hair’s strength and structure from within is equally important. Collagen is a key protein that plays a role in maintaining the integrity of hair follicles, as well as the health of your scalp and skin. As we age, our natural collagen production declines, which can affect the quality and thickness of hair over time.

Taking a daily collagen supplement can support the structural building blocks that keep hair strong and help promote a healthy scalp environment. Although it will not directly prevent hair colour from fading, collagen may help your hair remain resilient and shiny, giving you better results from any dye you use.

Final Thoughts

Head and Shoulders can cause some fading in coloured hair, especially if it is used often or soon after dyeing. However, it does not remove hair dye in a dramatic or damaging way unless used intentionally for that purpose. If you rely on this shampoo to manage dandruff or scalp discomfort, it can still be part of your routine, particularly if you take extra steps to nourish and protect your colour.
