I used to have similar problem, so here are few things that helped me:
Applying a warm compress to the area can help soften the skin and may encourage the ingrown hairs to break through.
Exfoliation: Gently exfoliating the area can help remove dead skin cells and may free the ingrown hairs. You can use a mild scrub or a soft brush.
Topical Treatments: Over-the-counter treatments containing salicylic acid or glycolic acid can help reduce inflammation and promote exfoliation.
Avoid Picking: Try not to pick at the area, as this can lead to infection or scarring
