Here’s how often you should wash your hair, according to a dermatologist

 

How often should we wash our hair? Experts recommend 3 to 5 times a week, depending on the needs of our scalp and daily habits.

Maintaining a clean scalp is key to healthy, vibrant hair. Most experts say the optimal frequency of washing is typically three to five times a week. However, the exact number depends on your hair type, scalp condition, and lifestyle.

Regular washing prevents the accumulation of dirt and sebum, removes unpleasant odors, and makes subsequent care, such as applying masks, serums, or treatment products, easier.

Is it a myth that frequent washing makes hair oily?

Dermatologist Alex Docampo categorically rejects the common claim that frequent washing can “stimulate” excessive oiliness in hair.
According to him:

“Many people believe that washing frequently damages their hair or that washing more often causes the scalp to produce excess sebum. This is simply not true. It’s important to tailor your routine to the needs of your own scalp.”

Are 3-5 washes per week appropriate?

This frequency helps:

remove sebum and residues of styling products

hair follicles can “breathe” better

reduce the risk of irritation

control unpleasant odors

limit the growth of bacteria and fungi, especially in hot weather and when sweating

Of course, everyone’s scalp has different needs. People who exercise daily, live in a hot climate, or wear a helmet/hat at work may need to wash their hair more frequently.

Experts emphasize: routine should be individual.

The Hair Surgery Institute explains that the ideal washing frequency varies depending on:

hair type (oily, dry, normal, curly)

condition of the scalp

daily activities

type of styling products

preferred hairstyle (tail, bun, loose hair)

Therefore, there is no “universal formula” – it is important to monitor your own needs.

What are the risks of over-diluting shampoo?

accumulation of sebum

itching and peeling of the skin

unpleasant smell

folliculitis

temporary hair loss in people with sensitive scalp

Dermatologist Dr. Maria Marcos adds that for people with oily skin, stress can exacerbate oiliness, making washing even more necessary.

How to properly care for your hair

To keep your hair healthy:

If you have a sensitive scalp, choose a balancing shampoo or a gentle sulfate-free shampoo.

Apply conditioner only to the lengths and ends, never to the roots.

Use a nourishing mask once a week.

Avoid very hot water as it increases oiliness and dries out the ends.

Massage your scalp with your fingertips, not your nails.

Rinse the product thoroughly – any residue will cause itching and a feeling of heaviness.

Do not go to bed with wet hair to prevent breakage and the development of fungal infections.

Volume and shine enhancing ranges, as well as tints that conceal ingrown roots, are often cited as examples of useful products.

Conclusions

If you need a simple guideline, washing your hair three to five times a week is the most sustainable and recommended option for most people. It’s important to adapt your routine to your lifestyle, climate, activity level, and individual scalp needs.
