  • There's a movement that is upending shower routines across the country.


  • There's a new trend in the beauty world, it's called the No Poo Method.


  • The secret could be not shampooing.


  • Skip the shampoo.


  • Your hair is better off without it.


  • At least that's the slogan for the No Poo Movement that's got people claiming they haven't used conventional shampoo in years.


  • And their hair looks amazing.


  • But is this just a fad?


  • What would really happen if you didn't shampoo your hair for an entire year?


  • To find out, we asked dermatologist Angela J. Lamb, M.D., from Mount Sinai Hospital in New York.

    我們邀請紐到約西奈山醫院的皮膚科醫學博士 Angela J. Lamb 來替我們解惑。

  • So what shampoos do mostly is they do what's called saponification.


  • So their actual shampoo comes along and wraps around oil and dirt, and when you rinse, it kinda comes out with the shampoo.


  • You kinda rinse out both the shampoo and the oil and dirt.


  • But most conventional shampoos are too good at what they do, stripping away too much oil from your hair to the point where you start producing extra oil to compensate.


  • As a result, after the first few days without using shampoo, your hair will look and feel way more oily than normal, especially if you have straight hair.


  • So for people that have straighter-patterned hair, like I said, what happens with that patterned hair is, the oils, the sebum, tend to progress down the hair shaft faster.


  • So their hair is going to feel oilier, dirtier sooner.


  • After a month of no shampoo, that oil will have caught a good amount of dead skin cells, dirt, and possibly even bacteria, which could start to make your scalp itchy and even smell kind of funky.


  • I would say if you go longer than about a month, that you may see some, again, what you would get is sometimes odor, you would get some trapping of bacteria on your scalp.

    我個人意見是,如果超過一個月不用洗髮精,你可能發現... 你的頭皮有時可能會發出異味,也可能滋養出細菌。

  • After six months to a year, all that gunk can clog up your hair follicles, which can prevent new hair from growing.


  • And over time, ultimately lead to hair thinning or even hair loss.


  • There's also a risk of your scalp getting infected from all the bacterial buildup.


  • So the signs you want to look for that would be problematic, that are telling you you're not washing your hair often enough are:


  • scale, odor, sometimes pimples that lead tothat are basically saying you're getting an infection or bacteria.

    積垢、臭味、以及偶發的粉刺都會導致... 基本上它們都在傳達頭皮已受感染或有細菌的訊息。

  • Those would be the signs that you would know that you're not washing often enough.


  • But here's the thing: Rinsing your hair with gentle cleaning agents like baking soda or even just plain water is often enough to prevent itching, hair loss, and infection.


  • So, how often should you be rinsing?


  • So, to not wash at all, to use no water, no cold washing, no detergent, shampoo—I think the cutoff for how long you can go really does depend on your styling pattern.

    所以說完全不洗頭,不用水洗、不冷洗、不用清潔劑或洗髮精... 我認為時間點完全取決於你的頭髮造型模式。

  • So, many people can do that for a couple of days, some people can do it longer, I would say two to four weeks.


  • For example if your hair is locked or if you have any kind of prosthetic in your hair like a weave or a braid,


  • you often can go a little bit longer just because of the way the hair is kind of tied down and not getting as disrupted.


  • So, if you would like to wash your hair less frequently, try to go maybe I'd say about three days to a week and see how you do.


  • So you should still wash and rinse, but you don't have to repeat every single day.


  • Just try it out and see how you do.


There's a movement that is upending shower routines across the country.
