Experts have devised a formula for what they believe is the perfect hair wash.
Tests were carried out over six-months on more than 500 volunteers to examine different methods of wetting, lathering and rinsing hair.
The result is a strict combination which differs depending on the length of the hair. The formula was devised by scientists at the research centre of beauty product brand Dove in Port Sunlight, Merseyside.
According to its scientists, only running water at a temperature of 36.7 C should be used. People with short hair should use no more than 6ml of shampoo, medium length 8ml, and long 10ml. Lathering should last 28 seconds and involve 20 rubs. Hair should then be rinsed for at least 22 seconds and repeated once to ensure cleanliness from the root to the tip.
The experts say conditioner is essential to complete the perfect wash. Again, the amount recommended depends on the length of hair - 2ml for short, 4ml for medium, and 6ml for long. The conditioner should be applied with a wide-toothed comb and left for 57 seconds before rinsing with water at 36.7 C. Finally, hair should be patted with a towel to absorb excess water, then left to dry naturally.
英国默西塞德郡德芙美容产品研究中心的专家们通过一项长达6个月的研究发明了一种“完美洗发”方式。这种方式是专家们研究了500多名志愿者湿发、洗发和过水的方法后得出的。
研究的结果显示，用于洗发的水的最佳温度是36.7摄氏度，而头发的长度不同，“完美洗发”的方式也不一样。短发的人使用的洗发香波不应超过6毫升；头发中等长度的人不应超过8毫升；而长发的人不应超过10毫升。使用香波擦头发的时间应持续28秒，包括20下按摩。过水应持续22秒，并且重复一次，确保从发根到发梢都清洗干净。
专家们称，护发素是完成“完美洗发”方式的关键，而使用护发素的多少同样取决于头发的长短。短发，2毫升；中等长度，4毫升；长发，6毫升。使用护发素的时候，应该用一把宽齿的梳子梳头，并且让护发素留在头发上57秒，然后再用36.7摄氏度的水冲洗。最后，用毛巾把轻拍头发把水吸走，并让头发自然风干。
