Can a dermaroller 1.5mm cause damage to hair follicles?

Hello,

Using a dermaroller with a needle length of 1.5mm on your scalp can be a bit aggressive, especially if you are not experienced with the technique. While it is designed to promote hair growth by stimulating blood flow and collagen production, improper use can potentially cause temporary damage or irritation.

Given that you did not apply much pressure and there was no bleeding, it is less likely that you caused significant damage to your hair follicles. The soreness you experienced is a common side effect and typically subsides within a day or two.

The thinning of your hair and the small patches you are noticing could be a result of the natural shedding phase that often occurs with the use of Finasteride and Minoxidil, especially within the first few months of treatment. This shedding is usually temporary and is a sign that your hair is going through its growth cycle, which can eventually lead to thicker and healthier hair.

However, if you continue to notice thinning or patches without improvement, it would be best to consult with a dermatologist to evaluate your scalp and hair health more thoroughly. They can provide personalized advice and ensure that your treatment plan is optimized for your needs.
