Welcome to HealthcareMagic forum,
What you have is called HIRSUTISM
.The best and permanent (long term) would be lasers,but before that I would like to tell the causes of it.
Facial and body hair can be because of idiopathic reason(i.e. no exact cause) ,to hormonal
(as in Poly-cystic ovary disease-PCOD ) or thyroid
cases or familial ...rarely it can also be because of some topical creams or oral tablets .Its important to diagnose the cause first .As you said it is thick and course ,that would mean that you should get your hormonal profile done .There are certain other feature which we look for in such cases like- acne(pimples), irregular periods
,weight gain & scalp
hair loss.If you have any of these,then you should get the hormone test done .These test are done on the 2nd day of your periods. You can even get a ultra sound
done for lower abdomen to rule out PCOD.If this comes positive then you should take hormonal medicines along with the lasers.
The best of the treatment is lasers which is a permanent treatment (strictly speaking long term) .Laser hair reduction requires multiple sessions at an interval of say 4-6wks.Normally one would require 6-8 sessions ,but if one has hormonal problem then you may need more touch ups.It is safe an effective...but you should go for it only if you have thick or moderately thick hair.Very fine hair may not show good result.Blonde or gray hair also don't respond well to lasers. Result also depends upon which laser machine you are going for.There are three basic types of lasers used --
1) IPL(intense pulse light)
2) Nd:yag laser
3) Diode laser.
The best of the lot is diode laser which is costly but very effective .The worst would be a IPL (which is actually not even a laser),its just a light device.Apart from its low effectiveness it has other disadvantages also like it can lead to burn marks.The probe of laser is big in size ,so its difficult to manipulate in smaller areas,and thus leads to big rectangular burn marks.Many doctors keep this machine as the cost of machine is less as compared to diode laser.Diode laser not only destroys the root of hair which is black but also the stem cells responsible for new growth of hair. Nd:yag laser comes next ,inferior to Diode laser.But if you don't get a diode in your place then you can go for Nd;yag.One thing you should remember before taking the laser ,that its not just the machine but the man behind the machine also which is important.I've been doing lasers myself for last 12 years now ,so I know in and out about lasers .I f you are further interested then you can visit my website www.skinhairclinc.com for details .
But remember don't take laser treatments from any beauty parlor,prefer a laser clinic run by a dermatologist
I hope this would help you decide which technique to go for .
