    清洗头发时的注意事项!
    发布时间:2014-03-02 浏览:

    上海快3最新开奖 www.ulks.net    洗净三千烦恼丝,洗去一头尘土,不仅令人神清气爽,对健康也大有裨益。但怎样正确洗头,其中有许多学问。有专家指出,早起或睡前洗头均不利健康。那么,如何健康洗头发呢?洗头发时大家容易犯下哪些错误呢?专家表示,健康洗头,跟洗的时间、间隔以及方式等密切相关。否则,可能引起头发干燥、断发、头皮屑增多、皮炎、脱发,甚至头痛等疾病。

        洗发时最容易犯的5个错

        1、头发没湿透就抹洗发水

        洗发之前,应先用水浸透头发,再抹洗发水,否则会造成清洗不彻底或打结。抹洗发水时,先将洗发水倒在手上,滴一些水,轻轻搓出泡沫再抹。

        2、用指甲抓头皮

        切勿用指甲抓头皮,应该用指腹轻轻按摩头皮,轻揉发丝,避免指甲划伤头皮。如果头皮毛囊发炎,用指甲抓会加重感染症状。

        3、洗发水挤太多

        很多普通洗发水含有容易导致头发水分流失的化学成分硫酸盐,如果使用过量,会使发丝干枯,产生头皮屑。事实上,很多人受电视广告误导,洗头发时一味追求泡沫丰富,其实,一般人只需一点泡沫就足以起到清洁作用。

        4、每次都用洗发水

        如今空气污染严重,再加上人们吃得好,头皮往往分泌过多油脂,导致许多人习惯每天洗头。但是,若使用洗发水的频率过高会导致头皮油脂丧失,使头发面临“唇亡齿寒”的危险。建议不必每次洗头都用洗发水,每周最多使用两次。

        5、洗完盘在头顶

        许多女性洗完头发习惯盘在头顶或扎起来,事实上,头发在未干时十分脆弱,容易打结或断裂。

        一周洗几次最好?次数根据具体情况定

        头皮中的皮脂腺和头发上的毛囊每天都在分泌油脂,其对头皮和头发具有?;ず腿蠡饔?,如果洗得过勤,会把这层油脂彻底洗掉,使头皮和头发失去天然?;つ?,变得干燥易分叉。为此,范主任表示,头发其实没必要天天洗,具体情况因人而异。

        一般情况下,以每周洗2~3次为宜;如果常在户外,油烟、灰尘又较大,可适当增加次数;而很少外出、头发又不油的人,一周洗一次也没关系。

        洗头姿势要得当

        洗头姿势也很重要,一般情况下,很多人喜欢低着头,把头发垂下来洗。但江苏省人民医院康复医学科主任励建安提醒大家,头长时间下垂会影响正常血液循环,造成脑供血不足,对头发生长也不利。因此淋浴时直立的洗头姿势较合适,而且要让身体调整到最舒服的状态。如果出现某部位疼痛、麻木或头晕等症状,说明血管或神经受到压迫,应适时调整。

        到理发店洗头对很多人来说是一种享受,但公共场所洗头的人既多且杂,洗发工具不免混杂细菌及病菌。

        皮肤过敏、对洗发水香料敏感的人需谨慎。此外,在理发店洗头,一般都采取仰躺姿势。但这种姿势并不是人人都适合,因为仰躺还对头部椎动脉造成一定压力,直接影响脑部的供血流量。时间久了会导致脑供血不足,从而可引起头晕、恶心、站立不稳等症状。

        老年人、高血压者、颈椎病患者尤其不宜仰着洗头,否则易导致晕眩、脑部短暂缺氧,甚至中风。

    Wash thousand strands of worry , wash away a dust, not only refreshing , but also of great benefit to health . But how to properly wash your hair , many of which knowledge. Experts have pointed out , wash before going to bed early or are detrimental to health. So, how healthy her hair too ? What wrong when her hair all easy to commit it? Experts said that a healthy shampoo , wash with time intervals and methods are closely related. Otherwise, it may cause dry hair, broken hair , increased dandruff, dermatitis , hair loss, headaches and even other diseases .

        Shampoo most likely to commit five wrong

        Before shampooing, hair should be soaked with water , add a touch of shampoo , otherwise it will cause incomplete cleaning or knotted . When wiping shampoo , first pour shampoo in your hand, drop some water , then wipe gently Cuochu foam .

        2 , grasping the scalp with nails

        Do not grasping the scalp with nails should be used gently massage the scalp, hair gently to avoid scratching the scalp nails . If the scalp hair follicle inflammation , infection with a fingernail grip aggravate the symptoms .

        3 , shampoo too crowded

        Many ordinary shampoo hair easily lead to loss of water containing the chemical composition of sulfate, if used in excess , will make the hair dry , resulting in dandruff. In fact, many people misled by television advertising , rich foam when the blind pursuit of her hair, in fact , most people only need a little bubble clean enough to play the role .

        4 , each with shampoo

        Today, air pollution , plus people eat well, often excessive secretion of scalp oils , resulting in many people used to wash your hair every day. However, if the frequency is too high to use shampoo can cause loss of scalp oils , make hair face " common lot " in danger. Recommendations do not always have to wash your hair with shampoo , use a maximum of twice a week .

        5 , washing the plate in the top of the head

        Many women used to dish washing hair in the head or tied up , in fact , when the hair is dry fragile , easy to tie or break.

        Several times a week is the best ? Times depending on the circumstances be

        Sebaceous glands and hair follicles in the scalp hair on a daily basis in the secretion of oil , scalp and hair with its protection and lubrication, if washed too often , this layer of grease will wash thoroughly , so that the scalp and hair loss natural protective film , becomes dry and easy fork. To this end, Fanzhu Ren said , in fact, no need to wash the hair every day , the circumstances vary.

        Under normal circumstances, to wash 2-3 times a week is appropriate ; If you often outdoors , smoke , dust and larger , may be appropriate to increase the number ; and rarely go out, people without hair oil , wash once a week it does not matter .

        To properly wash your posture

        Shampoo posture is also very important , in general , a lot of people like to head down, her hair hanging down to wash . But Li Jian , director of the Jiangsu Provincial People's Hospital Department of Rehabilitation remind everyone , long drooping head will affect the normal blood circulation , resulting in insufficient blood supply to the brain , the hair growth is also negative. So wash your hair in the shower upright posture more appropriate, and to let the body adjust to the most comfortable state. If there is a site pain , numbness or dizziness and other symptoms , indicating that the blood vessels or nerves are oppressed, should be timely adjusted .

        To the barber shop shampoo for many people is a pleasure , but people in public places shampoo as many and shampoo mixed bacteria and germs can not help tool .

        Skin allergies, shampoo fragrance for sensitive people need to be cautious . In addition, the barber shop shampoo , are generally taken supine posture. But this position is not suitable for everyone , because the supine also cause some pressure on the head of the vertebral artery , directly affect the brain 's blood flow . Over time will lead to insufficient blood supply to the brain , which can cause dizziness , nausea , staggering and other symptoms.

        The elderly, hypertension , cervical spondylosis , especially not upturned shampoo , otherwise easily lead to dizziness, brain transient hypoxia and even stroke.
