You’ve been using shampoo all wrong: here's how much you actually need

When it comes to washing your hair, many people assume that more shampoo and conditioner will lead to cleaner, healthier locks. In reality, using too much product can leave your hair feeling heavy, greasy, or difficult to manage.

How much shampoo should I use?

For most hair types, a coin-sized amount of shampoo is enough for short to medium-length hair, while those with longer or thicker hair may need slightly more. The key is to focus shampoo on the scalp rather than the lengths of your hair. Your scalp is where oil, sweat and product build-up accumulate, and the shampoo that rinses through your hair will be enough to cleanse the ends.

How much conditioner should I use?

Conditioner works differently. It should be applied mainly to the mid-lengths and ends, where hair tends to be drier and more prone to damage. Again, a coin-sized amount is usually sufficient, although thicker or longer hair may require a little extra.

What happens if I use too much shampoo or conditioner?

Using excessive amounts of product can actually make your hair harder to manage. Too much shampoo can strip away natural oils, while too much conditioner may weigh hair down and reduce volume.

How can I tell if I’ve used too much shampoo or conditioner?

If you're unsure whether you're using the right amount, pay attention to how your hair feels after washing. Healthy hair should feel clean, soft and manageable—not squeaky, greasy or coated.

Choosing products suited to your hair type and using them correctly can make a noticeable difference to the health and appearance of your hair between salon visits.
