If you have an ingrown hair that has turned into a cyst and has not resolved after several months, it is best to seek medical attention. Here are some general steps you can follow: 1. **Avoid Picking or Popping:** This can lead to further inflammation, infection, and scarring. 2. **Warm Compress:** Apply a warm compress to the area several times a day. This can help to soften the skin and bring the ingrown hair to the surface. 3. **Topical Treatment:** Over-the-counter treatments containing salicylic acid or benzoyl peroxide can be applied to the area. These can help reduce inflammation and potentially help the hair to surface. 4. **Professional Help:** If the above steps don't help or if the area becomes red, painful, or pus-filled, it's time to seek medical help. A dermatologist or other healthcare professional can safely drain the cyst if necessary and may prescribe antibiotics or other medications to treat or prevent infection. 5. **Prevention:** To prevent future ingrown hairs, consider exfoliating the area regularly, using a sharp, single-blade razor when shaving, and shaving in the direction of hair growth. If ingrown hairs continue to be a problem, you may want to consider other hair removal methods, such as laser hair removal. Remember, if you have any concerns about a skin condition, it's always best to consult with a healthcare provider or a dermatologist. They can provide advice tailored to your specific situation.
