Not every two days, not every four days: how often should you wash your hair, according to a dermatologist?

The reality is that there is no single schedule that works for everyone. Hair-washing frequency depends on several factors, including scalp type, lifestyle, physical activity, climate, and the products you use. What matters most is maintaining proper scalp hygiene while avoiding unnecessary irritation or buildup.
Dermatologists increasingly emphasize that a clean scalp is essential for hair comfort, freshness, and overall appearance. Regular washing helps remove excess oil, sweat, environmental pollutants, and styling residue that can accumulate over time. When done correctly and with suitable products, washing your hair does not increase oil production and does not damage the scalp.
Not every two days, not every four days: how often should you wash your hair, according to a dermatologist?
Experts recommend washing your hair between 3 and 5 times a week, depending on your scalp type and daily habits.
Scalp hygiene is key to healthy-looking hair. Experts agree that the ideal frequency is usually between three and five washes per week, depending on hair type and lifestyle. Washing your hair regularly prevents buildup, unpleasant odors, and facilitates any subsequent hair treatments.
Dermatologist Alex Docampo denies that washing hair frequently increases oiliness: “Many people think that washing their hair a lot is bad because it damages it, or that paradoxically, washing it more often produces more sebum and makes the hair dirtier, but this is completely false.” The important thing is to adapt your hygiene routine to your scalp.
Should you wash your hair 3 to 5 times a week?
This range of washes promotes the removal of sebum and product residue, improves follicle oxygenation, and reduces the risk of irritation. It also helps control odor and the proliferation of fungi and bacteria in warm environments. Each scalp will require adjustments depending on physical activity and climate.
The Hair Surgical Institute explains: “The frequency of hair washing can vary depending on different individual factors, such as hair type, daily activities, scalp condition, use of hair products, and hairstyles.” Therefore, the routine should be adapted to each person’s daily life. 
Risks of spacing out washes too much, according to experts
Not spacing out washes can lead to sebum buildup, itching, and flaking. Dr. María Marcos points out that “this is a very common condition due to multiple causes, including frequent stress in oily skin.” Inflammation of the follicle can even cause temporary hair loss.
To care for your hair, it is advisable to choose a balancing or sulfate-free shampoo depending on sensitivity, use conditioner on the mid-lengths and ends, and apply a hair mask weekly.
