<p>Lasers emit a wavelength of light with a single colour. When it is targeted to the skin, the energy from the light is transmitted to the skin and hair pigment melanin. As a result, this heats up and destroys the surrounding tissue. However, in order to permanently remove hair while minimising damage to the surrounding tissue, the laser must be targeted at specific cells. These cells are hair follicle cells which place in a part of hair called a hair bulge.&nbsp;</p>

<p>Laser treatment can either reduce hair density or eliminate unwanted hair. The permanent reduction in hair density means hairs can regrow after a single course of therapy and the patient will need to continue laser treatment. In the case of permanent hair removal, it means none of the hair of the treated area will regrow after a single course of treatment and none of the ongoing treatments is required.&nbsp;</p>

<h2>Different Colour Tone Require Different Time&nbsp;</h2>

<p><strong>White or Pale Skin-</strong> People with dark hair will typically achieve permanent hair removal with a minimum of 5-6 treatments every 4-5 week. However, people with fair skin tone will usually see permanent hair reduction after an initial course of treatment and will need 6-12 treatments spaced a month apart after that.</p>

<p><strong>Light Brown Skin-</strong> People with dark hair tone usually achieve permanent hair removal with almost 8-10 treatments every 5-6 weeks. On the other hand, people with fair hair will usually see permanent hair reduction after an initial course of treatment, which could necessitate 3-5 monthly follow-up treatments.</p>

<p><strong>Dark Brown- </strong>People with dark hair will typically achieve permanent hair reduction With 6-10 treatments every 4-6 weeks. Maintenance will usually be needed with 4-6 monthly repeat treatments.</p>
