When I first shaved my chest, it felt like Velcro the next day.
I then shaved one leg (calf) and home-waxed the other...the shaved leg had stubble within two days, the waxed was smooth for a week, then had soft hairs.
I decided to give professional waxing a try...and that's what I did until HRT kicked the hairs off my body.
The whole body might be $300+, so instead do areas...arms +upper chest/back may be $100, legs and lower back/chest may also be $100, Brazilian or bikini may be $40-$90.
Pro waxing generally lasts 4-8 weeks, but usually takes a bit longer to grow out as before.
