Underarm Hair Removal – Your Complete Guide

A Few Facts

Underarm hair, also termed axillary, is of a type known as terminal hair.

Terminal hair is thicker and tends to be darker than hair all over the body and develops on the face, armpits and pubic area following puberty.  Head hair is also terminal hair but has a much longer life cycle which is why it grows considerably longer.

The life cycle of hair varies depending on the part of the body where it is located and is genetically determined.

Other variables include age, ethnic background, gender and hair colour.

It is for these reasons that it is not possible to be entirely accurate, but the average life cycle of underarm hair is around 5 months.  Approximately 30% is in the actively growing stage at any one time.

What are the Options?

Basically, you have six options for removal of underarm hair, each of which have their merits and downsides. 

Shaving is probably the easiest and quickest method, and can be done in the shower as part of your daily routine.

Using a rechargeable electric shaver is particularly convenient and, although a razor will give a closer shave, nowadays electric shavers are almost as effective.

Depilatory creams produce good results, although they can be a little time consuming and messy.

Product development over the years has lead to a reduction in the offensively overpowering scent of the original depilatories, with some actually being relatively pleasant now.

The results are a little longer lasting than shaving.

Woman wax waxing underarm

Waxing is a very effective and long-lasting method for removing underarm hair, which you can do at home or have done for you in a professional salon.

It can be a painful method, especially when you first have it done, as the armpit is a sensitive area.  

Over time, with regular sessions, the skin will become more tolerant to the procedure.

We would recommend you go to a salon for the first few times, but if you are doing it at home make sure to hold the skin good and taut.

There are different types of wax, some which need heating, some that are used on pre-waxed strips and some that can be used without strips, so you may wish to experiment to see which suits you best.

Epilating is similar to waxing in that it pulls the hair out from the root.

Electric epilators have a series of anything up to 72 tiny tweezers on their rotating epilator head, to pull multiple hairs simultaneously so that they can be used for larger areas than the traditional manual tweezer.

The results will last as long as waxing and epilators are easy and convenient to use at home, some also have a shaving head attachment.

Laser underarm

IPL/Laser removal of underarm hair can give permanent results, leaving the area with reduced, finer/lighter regrowth.

There is a difference in technology between IPL and Laser hair removal, although both use light rays to target dark pigment in the hair to permanently disable the hair follicle.

The main thing to remember with IPL/laser hair removal is that you will need to have a number of sessions over several months to see results.

This is because it is only effective on hair that is in the actively growing stage.

Electrolysis is currently the only FDA approved method for permanent hair removal, and is carried out by professional clinicians.

It involves the insertion of tiny probes into the hair follicle to produce energy which permanently disables the follicle, causing the hair to fall out and the follicle to be unable to re-grow new hair.

As with IPL hair removal, many sessions will be required over a period of time to achieve the results you want.

One of the great advantages of electrolysis, though, is that it is safe and effective for all skin and hair types.
