Many people who value cleanliness wash their hair almost every day, thinking that this will ensure that their hair is clean every day. However, frequent hair washing not only does not protect the hair, but can also potentially damage it. Over-washing the hair can completely wash away the natural oils secreted by the sebaceous glands, causing the hair and scalp to lose their natural protective barrier, which is detrimental to the health of the hair. So, how often should hair be washed?
How often should hair be washed?
The frequency of hair washing cannot be generalized because everyone has different hair types.
How often should oily hair be washed?
Having oily hair can be quite bothersome. It feels uncomfortable when the hair becomes greasy within a day and many people with oily hair wash their hair every other day or even every day. The correct way to wash oily hair is once every one to three days. Washing the hair too frequently can damage the hair follicles. Therefore, it is best to wash oily hair every one to three days. Additionally, people with oily hair should drink plenty of water to maintain hydration in the body.
How often should dry hair be washed?
Dry hair is often dehydrated, resulting in dull and dry hair. People with dry hair should also maintain a good diet, drink plenty of water, and exercise regularly to ensure that the hair absorbs sufficient nutrients and stays vibrant. It is recommended to wash dry hair once every seven days.
How often should damaged hair be washed?
Hair can become damaged due to nutritional deficiencies or issues with the hair follicles, which can lead to hair loss. If the hair is not excessively greasy or dry, it is best to wash it as little as possible. Washing the hair too frequently can cause excessive hair loss, especially if the hair is already weak and prone to shedding. For oily hair, it is best to wash it every other day, while for normal hair, washing it every three to four days is fine.
How often should normal hair be washed?
If the hair falls between oily and dry hair, there is no need to wash it frequently. Generally, washing normal hair once every two to three days is fine. However, for people who engage in outdoor activities and are exposed to UV radiation and airborne impurities, the hair is more prone to damage. To avoid more severe damage to the hair, it is recommended to wash it daily.
Frequency of washing hair depends on the environment
During the summer and autumn seasons, it is best to wash the hair every other day. For people in certain professions that require higher hygiene standards, it is best to wash their hair daily. When washing the hair, pay attention to the choice of shampoo and try to avoid using highly alkaline shampoos. It is also recommended to use conditioner regularly.
Harm of not washing hair for a long time
Each hair strand is connected to sebaceous glands that continuously secrete sebum. Regular hair washing can effectively clean excessive sebum from the hair surface, reduce dandruff, and increase the shine and smoothness of the hair. Not washing the hair for a long time not only makes the hair dirty and affects its appearance, but it can also cause dandruff, scalp inflammation, and even hair loss.
Hair care tips
Best time to wash hair
The period from 10 pm to 2 am is the regeneration and active phase of scalp cells. Washing the hair before this time can promote the regeneration of scalp cells. The best time to wash the hair is from 1 pm to 10 pm. After 10 pm until morning, the scalp enters a relaxation and recovery phase, and excessive stimulation should be avoided.
Preparation before washing the hair
Before washing the hair, slowly comb it from the ends, then comb from the roots to the ends to smooth the hair and improve blood circulation. This will ensure thorough cleaning of the hair and facilitate the absorption of nutrients by the hair.
Choosing a mild shampoo
The shampoo should be mild in nature, such as those containing amino acids and active substances like proteins. Avoid using shampoos with alcohol and silicones. Shampoos without silicones have stronger cleansing abilities and do not damage the hair.
Proper use of shampoo
When washing the hair, pour the shampoo into the palm of the hand, lather it, and then apply it to the hair. Wash the hair from the roots to the ends and let the hair hang naturally. Use the fingertips to gently massage the scalp in all areas, repeating this process two to three times. Avoid pouring the shampoo directly onto the scalp, as it can leave chemical residues on the hair and damage it, leading to split ends and dandruff.
Drying the hair promptly after washing
After washing the hair, it is best to dry it promptly, especially if washing the hair at night. Sleeping with wet hair can lead to colds, headaches, and severe damage to the hair cuticles, causing hair loss and deterioration in hair quality. When the hair is wet, the cuticles are open, so combing wet hair can cause significant damage to the cuticles, resulting in frizzy hair after drying.
