Im on esthetician by profession. It's completely safe. I only wax. Would never shave. My hair is way to thick and coarse. Waxing over time comes back less thick and coarse & takes longer to grow back. Shaving does the opposite. It's 100% safe, but I would make sure the salon or spa is clean and ur esthetician is well experienced.
What do you mean by share the gel? Im guessing you're referring to sharing the wax, and in that case do not go to any salon that double dips the waxing sticks into the pot. I get brazilians done every month or so and its perfectly safe, you just might be a bit more sensitive to the pain because of your hormones. My hair was getting too thick and ingrown with shaving, i feel much more clean groomed down there now.
I plan to go back to getting them done because shaving is becoming an obstacle and I don't like how itchy I get. It may be a tad bit sensitive down there tho.
ouch!! lol but yes I know some women who got it done while pregnant
