洗头发频率应该是几天一次

最佳洗头时间：下午1：00到晚上9：00，适合洗头，因为这段时间是头皮再生期和活跃期，通过清洁和按摩，可以促进头皮细胞再生!

The best shampoo time: 1:00 p.m. to 9:00 p.m., suitable for shampoo, because this time is the scalp regeneration period and active period, through cleaning and massage, can promote scalp cell regeneration!

最不适合洗头的时间：晚上10：00到第二天上午，因为这段时间是头皮松弛和休整期，这段时间洗头容易造成脱发。

The most unsuitable time for shampoo: from 10:00 p.m. to the morning of the next day, because this time is the period of scalp relaxation and rest, which is easy to cause hair loss.

洗头最好选在白天温度稳定的时间，如午后或是下班回家稍事休息后。这样就有足够的时间让头发自然晾干，从而避免一些疾病的发生。如果由于上班的缘故，你无法正常洗头，只能是晚上或者早晨洗头，一定要先用干毛巾擦干，然后再用吹风机把头发吹干，最后再睡觉或者出门。女士洗完澡后，一定要注意擦干身体和头发，避免寒邪湿气乘虚而入，以免患上头痛、颈脖背痛，甚至引发一些妇科疾病。

It's best to wash your hair at a time when the temperature is stable in the daytime, such as in the afternoon or after going home from work for a short rest. In this way, there is enough time for the hair to dry naturally, so as to avoid the occurrence of some diseases. If you can't wash your hair normally due to work, you can only wash your hair at night or in the morning. Be sure to dry it with a dry towel first, then use a hair dryer to dry it, and finally go to bed or go out. After a bath, women must pay attention to dry their body and hair to avoid cold and dampness, so as to avoid headache, neck and back pain, and even some gynecological diseases.

每个人应根据自己的发质，以及季节和活动空间的不同，选择每周的洗头次数。Each person should choose the number of shampoos per week according to their hair quality, season and activity space.

油性发质：如果在夏季或油性发质者，由于皮脂分泌旺盛，头发油腻厚重凝聚，容易打结，不柔顺，因此夏季和油性发质者，应每天洗发一次或者隔一天洗一次，才能保证头发的清洁与健康。

Oily hair: if in summer or oily hair, due to the sebum secretion is exuberant, the hair is greasy, thick and condensed, easy to knot, not supple, so summer and oily hair, should be washed once a day or every other day, in order to ensure the hair clean and healthy.

中性或干性发质：清洁头发的频率可以调整为每2-3天一次。如气温升高或经常在户外运动者，头发容易受到强烈的紫外线和空气中粉尘的刺激，为避免发质受损，也可适当增加洗头次数。

Neutral or dry hair: the frequency of hair cleaning can be adjusted to once every 2-3 days. If the temperature rises or people often exercise outdoors, their hair is easily stimulated by strong ultraviolet rays and dust in the air. In order to avoid damage to the hair quality, they can also increase the frequency of shampoo appropriately.

脱发患者：除非是油脂性极强的人，否则建议减少洗头次数，原因有两个。一是脱发者本身处于退行期和休止期，洗头太多会让头发掉得更快，产生心理压力;第二，脱发患者的头发比较脆弱，在洗头过程中容易断发。脂溢性脱发患者可以2天洗一次头，普通脱发患者，3到4天洗一次头也是可以的。

Alopecia patients: unless it is very oily people, it is recommended to reduce the frequency of shampoo, there are two reasons. First, the hair loss itself is in the degenerative and resting period, too much shampoo will make the hair fall faster, resulting in psychological pressure; second, the hair of patients with hair loss is relatively fragile, easy to break in the process of shampoo. Patients with seborrheic alopecia can wash their heads once every 2 days, and patients with ordinary alopecia can wash their heads once every 3 to 4 days.

洗头的最佳水温以38度为宜，考虑个人的耐受能力，37℃~40℃的水温都是比较合适的。这种水冷热适度，能扩张皮肤毛细血管和真皮浅层血管，使汗孔开放，促进代谢废物排泄，因而去污比冷水强，特别是附着在发干上的尘垢更容易被清除，起到清洁头皮与头发、改善头皮血液循环、消除疲劳、振奋精神等作用。

The best water temperature for shampoo is 38 ℃. Considering personal tolerance, the water temperature of 37 ℃ ~ 40 ℃ is more appropriate. This kind of water cooling heat is moderate, can expand skin capillaries and superficial dermal blood vessels, make sweat pores open, promote the excretion of metabolic waste, so decontamination is stronger than cold water, especially the dirt attached to the hair stem is easier to be removed, play a role in cleaning the scalp and hair, improving scalp blood circulation, eliminating fatigue, invigorating the spirit and so on.
