Thank you for the information, please forgive my delay!
First of all, I would suggest avoiding any soap, vaginal shower or other on this area. I would only suggest, for the next few weeks, hygiene with clear water. Indeed, soaps can irritate or increase the risk of itching.
I suggest wearing clothes that are not tight and that allow breathing, like cotton clothes and underwear.
What I can suggest for the future is to avoid shaving against the directions of the hair and to avoid going over the area multiple times as this can greatly irritate and increase the risk of ingrown hairs and boils.
After shaving, only apply a fragrance-free moisturizer such as Aveeno, Base Glaxal or other.
If the situation persists despite the application of these measures, a doctor should be consulted, if only as a precaution.
Sincerely,
Tom Samaha, pharmacist
