How often should you wash your hair? As often as your scalp needs it. For some, that means washing every day; for others, every two to three days — or even less frequently. What matters most is keeping the scalp properly cleansed while choosing haircare products that support its natural balance.
Scalp and Hair Shedding: The Facts
The human body has around five million hair follicles, with approximately 100,000–150,000 hairs growing on the scalp. On average, hair grows a little over 1 cm per month — around 12–14 cm per year — while an individual hair can remain in its growth cycle for several years.
Daily hair shedding is a completely natural part of this cycle. Most people lose around 50–100 hairs a day as follicles continuously move through their different stages of growth, transition, rest, and renewal.
Hair growth rate, density, and strand diameter can also vary significantly from person to person, influenced by factors such as genetics, age, hormones, and overall health.
Hair colour has traditionally been associated with differences in average strand count and diameter, too. Naturally blonde hair tends to be finer but may occur at a higher density, while naturally red hair is often associated with thicker individual strands and a lower average number of hairs on the scalp.
How Often Should You Wash Your Hair — and What Causes It to Become Oily?
There is no universal answer to how often you should wash your hair. It largely depends on your scalp type, hair texture, lifestyle, and styling routine. Sebum — the natural oil produced by the scalp — plays a major role in how quickly hair begins to look and feel oily.
Fine, straight hair often loses its freshness and volume more quickly because sebum can travel easily from the roots along the hair shaft. Thicker, wavy, and curly hair, on the other hand, may stay fresh-looking for longer because natural oils take more time to move through the lengths.
Your haircare routine matters, too. Products that are too rich for your hair type — particularly heavy conditioners, masks, or styling formulas — can leave behind excess residue, weigh the hair down, and make it appear oily sooner. This is why choosing products suited to both your scalp and hair type is so important.
Washing Your Hair Daily vs Less Frequently: Which Is Better?
For years, there has been a persistent belief that washing your hair frequently causes it to become oily faster. In reality, how quickly your hair becomes greasy is influenced primarily by sebum production, your individual scalp, lifestyle factors, and the products you use.
If your scalp becomes oily quickly, washing your hair every day can be perfectly appropriate — provided you use a gentle shampoo suited to frequent cleansing.
Waiting too long between washes isn’t necessarily better. A build-up of sebum, sweat, styling products, and environmental impurities can leave the scalp feeling uncomfortable while making the hair look flat, heavy, and lacking in freshness.
The simplest rule? Wash your hair when your scalp needs it rather than following a rigid schedule.
How to Wash Your Hair Properly
Water temperature matters more than you might think. Very hot water can be uncomfortable for the scalp and may contribute to dryness, while lukewarm water is generally a gentler choice that still cleanses effectively. Aim for a comfortable temperature close to body temperature.
When shampooing, focus primarily on the scalp and roots, using your fingertips to massage the product in gently. There is no need to vigorously scrub or tangle the lengths — as you rinse, the lather will naturally travel through the rest of the hair and help remove impurities.
For some people, double cleansing can be particularly useful — especially when there is significant oil, sweat, dry shampoo, or styling-product build-up. The first cleanse helps remove surface residue, while the second allows for a more thorough cleanse of the scalp. However, double shampooing isn’t essential at every wash; adjust it to what your scalp actually needs.
Try: The Signature Shampoo by LUÃRE — designed to cleanse effectively while supporting a fresh, balanced-feeling scalp and naturally radiant hair.
After shampooing, follow with conditioner to replenish moisture, improve manageability, and reduce friction during detangling. Apply it mainly through the mid-lengths and ends rather than directly to the scalp, unless the product is specifically designed for scalp use.
Try: The Signature Conditioner by LUÃRE — a nourishing step designed to leave the lengths soft, smooth, and beautifully conditioned without compromising their natural movement.
Drying technique is just as important. Wet hair is particularly vulnerable to mechanical stress, so avoid vigorously rubbing it with a towel. Instead, gently squeeze or blot away excess water using a soft, absorbent fabric.
Try: The Hair Hug Towel™ by LUÃRE — a lightweight microfibre towel designed to absorb excess moisture gently while minimising unnecessary friction.
Heat styling — whether with a blow-dryer, straightener, or curling iron — can place additional stress on the hair fibre, particularly at higher temperatures. Keep heat exposure moderate, use appropriate heat protection, and choose a lower temperature whenever possible.
Final Thoughts
How often you wash your hair should be guided by the needs of your scalp rather than a rigid set of rules. Hair that becomes oily quickly may benefit from daily or every-other-day washing, while normal or dry hair may only need cleansing two or three times a week.
The key is to pay attention to how your scalp and hair respond and choose a routine that supports their natural balance. Regular yet gentle cleansing helps keep the scalp fresh and comfortable while maintaining healthy-looking, lightweight, and naturally radiant hair.
