I shave, so my armpit hair grows so quickly and very dense. Even after shaving it's not baby skin soft, or 100% gone.
What is the best way to care for armpit hair?
And is there a way to leave the armpit soft, and bare after shaving?

Thank you

Have you tried waxing??

Or perhaps Nair?

I have very dark course underarm hairs too... I have to shave upward, downwards, then left and right to make sure its least visible...

How often do you shave?

Shaving does leave the area a bit rough.
Waxing or sugaring would help tons! But it can get expensive buying the stuff. So here's a recipe for a homemade sugaring treatment that will help you save some money.

Also, moisturise the area at night. Preferably with cocoa butter.

Hey mostly all the nair products are on for sale for 3.95 I think. I got the sensitive 1 and it really works.

At CVS

Why bother shaving? Or removing the hair for that matter. Stay natural.Wash regularly... use the right deo... that's it.

I always shave my armpits in the shower... it softens the hairs and makes it easier to remove them.

Moisturise afterwards as well as shaving actually takes off a very thin layer of skin and the new skin dries out easily.

Try a sharper razor. I switched from two blades to three, and upgraded from super cheap to a little more expensive and found it made a huge difference.
