   洗凈三千煩惱絲，洗去一頭塵土，不僅令人神清氣爽，對健康也大有裨益。但怎樣正確洗頭，其中有許多學問。有專家指出，早起或睡前洗頭均不利健康。那么，如何健康洗頭發呢？洗頭發時大家容易犯下哪些錯誤呢？專家表示，健康洗頭，跟洗的時間、間隔以及方式等密切相關。否則，可能引起頭發干燥、斷發、頭皮屑增多、皮炎、脫發，甚至頭痛等疾病。

    洗發時最容易犯的5個錯

    1、頭發沒濕透就抹洗發水

    洗發之前，應先用水浸透頭發，再抹洗發水，否則會造成清洗不徹底或打結。抹洗發水時，先將洗發水倒在手上，滴一些水，輕輕搓出泡沫再抹。

    2、用指甲抓頭皮

    切勿用指甲抓頭皮，應該用指腹輕輕按摩頭皮，輕揉發絲，避免指甲劃傷頭皮。如果頭皮毛囊發炎，用指甲抓會加重感染癥狀。

    3、洗發水擠太多

    很多普通洗發水含有容易導致頭發水分流失的化學成分硫酸鹽，如果使用過量，會使發絲干枯，產生頭皮屑。事實上，很多人受電視廣告誤導，洗頭發時一味追求泡沫豐富，其實，一般人只需一點泡沫就足以起到清潔作用。

    4、每次都用洗發水

    如今空氣污染嚴重，再加上人們吃得好，頭皮往往分泌過多油脂，導致許多人習慣每天洗頭。但是，若使用洗發水的頻率過高會導致頭皮油脂喪失，使頭發面臨“唇亡齒寒”的危險。建議不必每次洗頭都用洗發水，每周最多使用兩次。

    5、洗完盤在頭頂

    許多女性洗完頭發習慣盤在頭頂或扎起來，事實上，頭發在未干時十分脆弱，容易打結或斷裂。

    一周洗幾次最好？次數根據具體情況定

    頭皮中的皮脂腺和頭發上的毛囊每天都在分泌油脂，其對頭皮和頭發具有保護和潤滑作用，如果洗得過勤，會把這層油脂徹底洗掉，使頭皮和頭發失去天然保護膜，變得干燥易分叉。為此，范主任表示，頭發其實沒必要天天洗，具體情況因人而異。

    一般情況下，以每周洗2～3次為宜；如果常在戶外，油煙、灰塵又較大，可適當增加次數；而很少外出、頭發又不油的人，一周洗一次也沒關系。

    洗頭姿勢要得當

    洗頭姿勢也很重要，一般情況下，很多人喜歡低著頭，把頭發垂下來洗。但江蘇省人民醫院康復醫學科主任勵建安提醒大家，頭長時間下垂會影響正常血液循環，造成腦供血不足，對頭發生長也不利。因此淋浴時直立的洗頭姿勢較合適，而且要讓身體調整到最舒服的狀態。如果出現某部位疼痛、麻木或頭暈等癥狀，說明血管或神經受到壓迫，應適時調整。

    到理發店洗頭對很多人來說是一種享受，但公共場所洗頭的人既多且雜，洗發工具不免混雜細菌及病菌。

    皮膚過敏、對洗發水香料敏感的人需謹慎。此外，在理發店洗頭，一般都采取仰躺姿勢。但這種姿勢并不是人人都適合，因為仰躺還對頭部椎動脈造成一定壓力，直接影響腦部的供血流量。時間久了會導致腦供血不足，從而可引起頭暈、惡心、站立不穩等癥狀。

    老年人、高血壓者、頸椎病患者尤其不宜仰著洗頭，否則易導致暈眩、腦部短暫缺氧，甚至中風。
