1, armpit hair is not hair, hair is very fine cilia on the body belonging to hair; And armpit hair belongs to long hair.

2. "The armpit is too dark to wash off" has nothing to do with the armpit hair itself.

It is found that the armpits are very dark, and there are four factors:

1, scrape off the hair roots left by armpit hair. If the armpit hair is thick, the thick hair roots left after shaving will look black. In this case, it must be "indelible" and only plucked.

2, there are many wrinkles under the armpit. Many skin wrinkles are "squeezed" together and look very black. This situation is also "indelible." Relatively speaking, the wrinkles of fair skin will be shallow, so it may be improved by using skin care products or beauty instruments that can whiten skin.

3, skin pigmentation. Some people will have skin pigmentation in armpits, behind knees, inside thighs and genitals. It is not clear why pigmentation occurs. This situation is also close to "indelible", and it has been reported that the use of "hydrogen peroxide solution (hydrogen peroxide)" with oxidative bleaching effect has a certain effect.

4. Local dirt. My armpit hair is thick, and I don't need shower gel or soap to clean this part at ordinary times, which will cause dirt accumulation. After shaving the armpit hair, I found that my armpit was so dirty. This situation is easy to handle. Use a strong cleansing shower gel or soap, plus a bath ball or loofah, I believe it will make your armpits white.
