Hair Bleaching: Methods, Laser Treatment and Points to Consider

Hair bleaching aims to make hair less visible by lightening its colour; it does not remove the hair. It may be preferred especially for fine but dark hair on the face, arms and abdomen. This article explains hair bleaching methods, laser treatment, its limits and points to consider.

Hair Bleaching Methods

• Home bleaching products: these usually contain hydrogen peroxide and lighten the hair temporarily.
• Laser hair bleaching: some laser devices are used to lighten the colour of the hair; it is performed after assessment by a doctor.

Home products can irritate and burn the skin. Before using them on sensitive areas such as the face, they should be tested on a small area, the product instructions should be followed, and they should not be applied to irritated skin or skin with wounds or pimples. Methods such as applying lemon or chamomile and sitting in the sun can damage the skin and cause pigmentation; they are not recommended.

How Is Laser Hair Bleaching Done?

The doctor first assesses the hair and skin and decides whether the treatment is suitable. The eyes are protected with special glasses during the treatment; a mild pricking or warm sensation may be felt with the laser pulses. The number of sessions and the interval are determined according to the hair type and the area. The effect is temporary and the hair may darken again. Laser hair bleaching is not the same as laser hair removal, which aims to reduce hair permanently; very light or white hair may not respond well to hair removal, and a doctor's assessment is needed on this.

Who Should Not Have It?

The treatment is not performed, or is postponed, if there is an active infection, a cold sore, an open wound or sunburn in the treatment area, after recent intense sun exposure, or if medicines that increase sensitivity to light are being used. During pregnancy and in people with darker skin, a doctor's assessment is needed first.

Possible Side Effects

Redness, mild swelling and sensitivity may occur after laser treatment; these usually settle quickly. Less commonly, burns, blistering, crusting and colour changes in the form of darkening or lightening of the skin may develop; this risk is higher in darker skin. Sunscreen should be used and the area protected from the sun in the days after the treatment. If increasing pain, blistering or discharge is noticed, a doctor should be consulted.
