At Swiss Der\u00adma Cli\u00adnic, four to eight tre\u00adat\u00adments are usual\u00adly appro\u00adpria\u00adte depen\u00adding on hair and skin type, spa\u00adced four to eight weeks apart. In indi\u00advi\u00addu\u00adal cases it can be fewer or more, becau\u00adse body area, hair colour, hair thic\u00adk\u00adness and hor\u00admo\u00adnes all play a part. \u201ePer\u00adma\u00adnent\u201c here means a long-term reduc\u00adtion in hair growth, not a pro\u00admi\u00adse that no hair will ever grow&nbsp;again.<\/p>\n<h2>Why one session is not enough<\/h2>\n<p>In <a href=\"https:\/\/swissdermaclinic.ch\/en\/glossary\/laser-hair-removal\/\">laser hair rem\u00adoval<\/a>, the pig\u00adment mela\u00adnin in the hair absorbs the light ener\u00adgy. This crea\u00adtes heat, which dama\u00adges the hair fol\u00adlic\u00adle. It works main\u00adly on hairs in the acti\u00adve growth phase.<\/p>\n<p>Not all hairs are in this pha\u00adse at the same time, so each ses\u00adsi\u00adon only rea\u00adches some of them. Fol\u00adlow-up appoint\u00adments are meant to reach the hairs that were res\u00adt\u00ading last time. That is why you need a series with inter\u00advals rather than one stron\u00adger treatment.<\/p>\n<h2>What the number of sessions depends on<\/h2>\n<p>Four to eight tre\u00adat\u00adments is a gui\u00adde, not a fixed plan. We dis\u00adcuss rough\u00adly how many ses\u00adsi\u00adons you are likely to need after exami\u00adning the are\u00adas con\u00adcer\u00adned.

Befo\u00adre start\u00ading a lon\u00adger series, check whe\u00adther your hair is sui\u00adta\u00adble for the treatment.<\/p>\n<\/blockquote>\n<h2>Preparation and the first session<\/h2>\n<p>For the tre\u00adat\u00adment to work, the hair root must stay in the hair shaft. The main points befo\u00adre your appointment:<\/p>\n<ul>\n<li>Stop pluck\u00ading, waxing, epi\u00adla\u00adting and suga\u00adring at least three weeks before\u00adhand. You can still&nbsp;shave.<\/li>\n<li>Do not bleach or ligh\u00adten the&nbsp;hair.<\/li>\n<li>Avo\u00adid inten\u00adse sun and tan\u00adning beds in the days befo\u00adre and after, and use sun\u00adscreen with SPF&nbsp;50.<\/li>\n<li>Shave the are\u00adas the evening befo\u00adre. On the day of tre\u00adat\u00adment, the skin should be fresh\u00adly washed and free of make-up, deodo\u00adrant and sunscreen.<\/li>\n<li>Men\u00adti\u00adon any tan, pre\u00advious pro\u00adble\u00adma\u00adtic scars, recur\u00adring cold sores and all medi\u00adci\u00adnes and sup\u00adple\u00adments during the con\u00adsul\u00adta\u00adti\u00adon. Plea\u00adse do not stop any medi\u00adca\u00adti\u00adon on your&nbsp;own.<\/li>\n<\/ul>\n<p>Allow about an hour for your first ses\u00adsi\u00adon, inclu\u00adding pre\u00adpa\u00adra\u00adti\u00adon and after\u00adca\u00adre. Our team checks the tre\u00adat\u00adment are\u00adas as well as pig\u00adment chan\u00adges and <a href=\"https:\/\/swissdermaclinic.ch\/en\/how-often-should-moles-be-checked\/\">moles<\/a> with a der\u00adma\u00adto\u00adscope and covers them if neces\u00adsa\u00adry. The laser pul\u00adses can feel like brief warm pin\u00adpricks, and the coo\u00adling on the device eases the sen\u00adsa\u00adti\u00adon of heat. Sui\u00adta\u00adble eye pro\u00adtec\u00adtion is essential.<\/p>\n<p>After\u00adwards, red\u00adness, swel\u00adling and sen\u00adsi\u00adti\u00adve skin are pos\u00adsi\u00adble. Blis\u00adters, pig\u00adment chan\u00adges, burns or scars occur rare\u00adly. Plea\u00adse cont\u00adact us if you deve\u00adlop blis\u00adters, crusts or seve\u00adre dis\u00adcom\u00adfort so that the skin can be asses\u00adsed befo\u00adre the next appoint\u00adment. You can return to work the same&nbsp;day.<\/p>\n<h2>The treatment timeline<\/h2>\n<p>The ide\u00adal inter\u00adval is usual\u00adly four to eight weeks and depends on the natu\u00adral hair cycle, the body area and how your skin reacts. As an exam\u00adp\u00adle: six ses\u00adsi\u00adons six weeks apart add up to around seven months from the first appoint\u00adment to the last.

Many pati\u00adents remain lar\u00adge\u00adly hair-free for months or even years after a series. Most will even\u00adtual\u00adly noti\u00adce some regrowth, though the\u00adse hairs are often finer, ligh\u00adter and fewer in num\u00adber. A touch-up can then be useful. The\u00adre is no fixed annu\u00adal appoint\u00adment, howe\u00adver: what counts is the actu\u00adal regrowth.<\/p>\n<p>Women\u2019s facial hair is a spe\u00adcial case. With <a href=\"https:\/\/swissdermaclinic.ch\/en\/facial-hair-laser-treatment\/\">laser hair rem\u00adoval on the face<\/a>, hor\u00admo\u00adnes have a strong influence, so a per\u00adma\u00adnent result like that on most other parts of the body can\u00adnot be expec\u00adted the\u00adre. The upper lip and chin can grow hair again even after a suc\u00adcessful series.<\/p>\n<h2>When a medical assessment matters<\/h2>\n<p>Hea\u00advy hair growth is not always just a cos\u00adme\u00adtic issue. If women deve\u00adlop thick, dark hair on the face or body along with irre\u00adgu\u00adlar peri\u00adods, the cau\u00adse should be inves\u00adti\u00adga\u00adted. If strong dark hair growth starts sud\u00adden\u00adly or your voice beco\u00admes deeper at the same time, a prompt medi\u00adcal exami\u00adna\u00adti\u00adon is important.<\/p>\n<p>At Swiss Der\u00adma Cli\u00adnic in Zurich, <a href=\"https:\/\/swissdermaclinic.ch\/en\/laser-hair-removal-women\/\">laser hair rem\u00adoval<\/a> is car\u00adri\u00aded out by expe\u00adri\u00aden\u00adced prac\u00adti\u00adtio\u00adners under medi\u00adcal gui\u00addance or by the der\u00adma\u00adto\u00adlo\u00adgist.

Some cour\u00adses need fewer appoint\u00adments, others more. It depends on your skin, your hair, the body area and how you have respon\u00added so&nbsp;far.<\/p>\n<h3>Can I shorten the intervals?<\/h3>\n<p>Plea\u00adse do not chan\u00adge the inter\u00advals on your own. The appoint\u00adment should fit both hair growth and the skin\u2019s reco\u00advery. More fre\u00adquent laser ses\u00adsi\u00adons do not auto\u00adma\u00adti\u00adcal\u00adly reach more hairs. Dis\u00adcuss pre\u00adfer\u00adred dates and plan\u00adned trips ear\u00adly&nbsp;on.<\/p>\n<h3>Can I shave between sessions?<\/h3>\n<p>Yes, you can shave. The skin is more sen\u00adsi\u00adti\u00adve for a few days straight after tre\u00adat\u00adment, though. Avo\u00adid pluck\u00ading, waxing and epi\u00adla\u00adting throug\u00adhout the series, becau\u00adse the\u00adse remo\u00adve the hair root that the laser targets.<\/p>\n<h3>Do extra sessions help with light&nbsp;hair?<\/h3>\n<p>Usual\u00adly not relia\u00adbly, becau\u00adse the sui\u00adta\u00adble pig\u00adment is miss\u00ading.
