Hi Javier
It is hard to say whether it is truly folliculitis or not based on your description. Rash unfortunately needs to be seen (sometimes real life better than photos) before a diagnosis is made.
You could give a little more information on
- how long has the issue been?
- Any new drugs or medications?
- Change in shower gel and even clothes washing? I have seen patients who had an overhaul of products or change in detergents which had a contact dermatitis or irritation.
My honest opinion is – see someone you trust and has time to consult you thoroughly for your history. Rash is 80% history 20% examination.
Take care!
