Which type of derma roller works best for addressing hair loss? 19 y/o male, with oily / dry skin

When choosing a derma roller to address hair loss, especially for a 19-year-old male with oily facial skin and dry scalp skin, it's important to consider the needle size and material:

Needle Size: For hair loss treatment, a derma roller with needle lengths between 0.5mm to 1.5mm is generally recommended. For beginners, starting with 0.5mm is advisable to ensure comfort and safety. As you become more accustomed to the treatment, you might consider increasing to 1.0mm or 1.5mm for potentially more effective results.

Material: Opt for a derma roller with medical-grade stainless steel or titanium needles. Titanium is more durable and tends to stay sharper longer, making it a good choice for repeated use.

Frequency: It's typically recommended to use a derma roller for hair loss once a week or every other week, depending on the needle length and your skin's response.

Skin Preparation and Aftercare: Ensure the scalp is clean before use, and consider applying a topical treatment like minoxidil after derma rolling to enhance absorption. Moisturize the scalp if it tends to be dry, and always follow up with proper sterilization of the roller.

Consultation: It’s advisable to consult with a dermatologist before starting derma rolling, especially given your mixed skin type, to ensure it’s suitable and to discuss any additional treatments or precautions that might be necessary.

This approach can help in promoting hair growth while considering the specific skin characteristics and needs.
