Cheap, fast and convenient, the razor seduces many women when choosing their hair removal mode.

However, many received ideas and questions remain: hairs push back faster and thicker? Can we shave every day? All areas? So many questions to which Adam Boulding, director of scientific communication for the beauty brands of the Procter & Gamble group, including Braun and Venus, answers.

"You often have to change the blades of your razor"

True.

"For disposable razors, it depends on the frequency of use and the area to shave," says Adam Boulding.

However, as for blade changes, you exchange your razor when you feel it hangs on the skin when there are no more lubes around the blades. It's a good guide to know when it's time to change razors or blades.

"I can borrow the razor of my male alter-ego without worry"

False.

Adam Boulding insists that women and men shave and wax in different ways. "The products of our brands, for example, are specifically tailored to women's needs, for example, women often epilate in the shower or bath rather than above the sink - unlike to men - the shavers are ergonomically designed so that the handles can be used even with wet hands. " For men, this is not a specificity, so be wary when using a male razor in the shower, there is a risk of slipping and cutting.

Most female razors are flexible and pivoting, unlike male ranges. "This flexibility takes into account women's curves and hard-to-reach areas," continues Adam Boulding.

"The skin and the hairs are also very different, depending on the parts of the body, between men and women," he continues. Thus, the skin of the legs of women differs from that of the male face or the female armpit . On the legs, the skin is tighter, thinner and drier, so we put on razors with care and body butters, for example, to block moisture and leave legs smooth and hydrated.

"With the razor, the hair repels faster and more drastic"

False.

It's a myth!

Gillette scientists have done extensive testing on the effects of shaving on the growth, texture and color of male and female hair. Verdict? Shaving would not affect hair growth, or change the color or texture in any way.

However, we have the impression of thicker hairs ... "Shaving can change the way we feel the hair after hair removal, because it actually changes the shape of the tip of the hairs that grow again." However, says Adam Boulding, if you let your hair grow back completely, you'll find your old state.

"You can not shave all areas of the body with a razor"

False.

Technically, it is possible to shave the whole body. Some areas, more sensitive, can however be irritated to the passage of the razor.

"Shave every day damages the skin"

In the shower or not, nothing prevents the daily use of the razor, provided to properly hydrate his skin after.

"I have no more gel or shaving cream, I can use soap"

For Adam Boulding, shave gel is "required to have perfect smooth skin".

It keeps the hair hydrated and the skin lubricated as the razor slips.

The advice and more? "To have beautiful legs, they are washed (this is also true for the armpits) to remove the film of oil from the skin and perspiration.Applies a sufficient amount of shave gel, rich in moisture, before shaving to help keep the hair moist and make sure the razor glides easily. "

On the other hand, the soap is not a good ally to prepare the skin because it can block the razor because of the deposit that it creates. And so hurt you. As for the foam, it is formulated as gel, it is mainly a question of affinity with the texture of the product.
