Derma Roller caused hair shedding and scar on my scalp

I'm sorry to hear about your experience. It's understandable to feel upset when an at-home treatment doesn't go as planned. Here are a few points to consider:

Consult a Dermatologist: Given the changes you've experienced, it's important to see a dermatologist as soon as possible. They can assess the condition of your scalp and provide a tailored treatment plan.

Avoid Further Damage: Until you consult with a professional, it might be best to stop using the derma roller or any other treatments on your scalp. This will help prevent additional irritation or damage.

Potential Causes: The changes you're noticing could be due to several factors, including the depth of the needles, frequency of use, or improper cleaning of the roller. Using a used derma roller can also introduce bacteria, leading to infections or scarring.

Possible Treatments: Depending on the assessment, treatments could include topical medications, laser therapy, or other interventions to help promote hair regrowth and heal the skin.

Emotional Support: It's natural to feel low about changes in your appearance. Consider reaching out to a support group or a mental health professional to help you cope with these feelings.

Remember, a healthcare professional can provide the best advice after evaluating your specific situation.
