Oily hair: 1-2 days.
If you have oily hair, and as long as you don't wash your hair for one day, your hair will become greasy and your scalp will start to itch, then I suggest you wash your hair once every two days1-to ensure the cleanliness of your hair and the health of your scalp.
Normal or dry hair: Wash it every 2-3 days.
If it is neutral or dry hair, you can wash your hair every 2-3 days in winter. Because the oil secreted by the scalp has a certain nursing effect on the hair, it is really unnecessary to wash your hair every day in winter.
Hair loss patients: wash once every 2-4 days.
Too much shampoo in winter makes hair fall off faster and break more easily, which brings psychological burden to alopecia patients. If you are suffering from seborrheic alopecia, it is recommended that you wash your hair every two days. If you are a common alopecia patient, it doesn't matter if you wash your hair once every four days in winter.
There are these precautions for washing your hair in winter.
Wash your hair directly without combing your hair
"The skin doesn't exist, but the hair is connected." Scalp is very important for hair. Comb your hair with a wet comb before washing your hair, so that dirt and dust attached to your scalp can float on the surface, so that you can wash your scalp and hair at the same time. In order to avoid hurting the scalp, it is recommended to use a comb with wide teeth and round head.
Use shampoo as soon as your hair gets wet.
Many people pour shampoo on their heads as soon as their hair is soaked, but as everyone knows, they can't wash their hair clean at all. Before using shampoo, rinse hair and scalp with warm water for more than 1 min to remove 70% to 80% dirt. Then, pour the shampoo into the palm of your hand, add water to make foam, and then apply it to your hair, so that the foam is richer and you can wash your hair thoroughly.
Scratch your scalp with your nails when you wash your hair.
There are many bacteria in nails, and once the delicate scalp is scratched, it is easy to induce infection. When applying shampoo, gently push the scalp with your fingertips to decontaminate and promote blood circulation.
Apply conditioner to hair roots.
Because the hair follicle is open when washing hair, the conditioner is coated on the hair root, and the chemicals inside can easily penetrate and block the hair follicle. It is recommended to straighten your hair first and apply it to the hair tip near your ears. Be sure not to let the conditioner touch your scalp.
The conditioner is not rinsed clean.
Many people think that leaving some conditioner in your hair can make your hair more moist. In fact, the residual conditioner is easily mixed with dust, attached to the scalp, blocking hair follicles and causing inflammation. Therefore, the conditioner must be rinsed after being applied.
Sleep with wet hair
When the hair is wet, the hair scales open, and the hair is delicate and not resistant to friction. If you sleep in a semi-wet and semi-dry state, it will cause the cuticle to become thinner and make your hair dry.
Go out immediately after washing your hair.
Studies have found that hair receives more than twice as much ultraviolet radiation as face. Ultraviolet rays will make hair scales thin and fall off. Go out immediately after washing your hair. Ultraviolet rays can easily cause hair to break and split. If you go out, you'd better take an umbrella or wear a hat to prevent ultraviolet rays.
