How often should I wash my hair?

Many of my clients ask how often they should be washing their hair. The truth is, while there are general guidelines, there is no one-size-fits-all answer. The right routine depends on several factors, including age, hair texture, scalp condition, and the products being used.

For those who are younger with a full head of hair and a normal to dry scalp, washing once or twice a week is often sufficient. If the hair is very dry, coarse, or brittle, washing once a week may be enough. Hair texture also plays a big role—curlier or drier hair types typically require less frequent washing.

The type of cleanser matters as well. If you are using a gentle, sulfate-free cleanser without harsh ingredients like sodium lauryl sulfate or sodium laureth sulfate, you can wash your hair more frequently—even daily in some cases. Some hair types, especially curls, benefit from being refreshed regularly. This may mean wetting and conditioning the hair daily, while only shampooing two to three times per week.

For fine, thin, and oily hair, washing the scalp with a mild cleanser two to three times a week—or more if needed—is ideal. Conditioning should still be focused on the ends to maintain moisture without weighing the hair down.

For medium or normal-textured hair with a normal to dry scalp, washing about twice a week works well. While washing once a week may be okay occasionally, consistently doing so—especially when only using conditioner or co-washing—can lead to buildup and clogged hair follicles.

As we age, hormonal changes and increased cortisol levels can impact scalp health and contribute to thinning. In these cases, washing only once a week may not be sufficient and could exacerbate these issues. A routine of washing two to three times per week is generally more supportive of scalp and hair health.

In addition to washing, brushing the scalp can be beneficial, as it helps stimulate circulation and distribute natural oils. Just be mindful of when you brush—avoid doing so right before styling if you want to maintain defined, separated curls.

Ultimately, listening to your hair and scalp is key. Adjust your routine based on how your hair feels, looks, and responds over time.
