Hair loss can be hereditary. Hereditary hair loss is called androgenetic alopecia, or for males, male pattern baldness, and for females, female pattern baldness.
脫發(fā)有可能是遺傳性的。遺傳性脫發(fā)又稱為雄激素源性脫發(fā)，分為男性雄性脫和女性雄性脫。

?Keep cool: In general, the less heat you use, the better. Styling with heat can damage the hair, and if you must use heated tools, pick those with adjustable settings and keep them on the lowest level.
讓頭發(fā)涼爽點(diǎn)：給頭發(fā)帶去的熱量越少越好。用熱風(fēng)做造型很損害發(fā)質(zhì)。如果一定要用加熱工具，用可調(diào)節(jié)溫度的并把溫度調(diào)至最低檔。
?Brush with care: Used in conjunction with a blow-dryer, round metal brushes can heat up significantly, and some brushes with hard plastic or metal bristles can cause breakage. Instead, try a brush made of gentle boar bristles or flexible nylon.

?Switch your part: Hair tends to lie flatter against the scalp when brushed repeatedly in the same direction; if you typically part your hair on the left, flip it to the right, so it's more likely to stand away from your scalp and look more voluminous.
換個(gè)分縫方向：如果你總是把頭發(fā)往同一個(gè)方向梳，頭發(fā)就會趴在頭皮上。所以如果你習(xí)慣往左邊分縫的話，就把頭發(fā)甩到右邊去，這樣你的頭發(fā)就更容易從頭皮上“站”起來，看起來更濃密。
