Derma rollers have become popular for promoting hair regrowth by stimulating the scalp and increasing blood circulation. But is a 1.5mm derma roller safe to use at home for this purpose?
What is a 1.5mm Derma Roller?
A 1.5mm derma roller features microneedles that are 1.5 millimeters long. This size penetrates deeper into the skin compared to shorter needles (0.25mm or 0.5mm), making it suitable for treating issues like hair thinning and bald patches by reaching the hair follicles more effectively.
Safety and Effectiveness
- Experts generally consider 1.5mm derma rollers safe for scalp use but recommend caution:
- Professional Supervision Recommended: Due to the depth of needle penetration, many dermatologists advise that 1.5mm microneedling sessions be performed by professionals to reduce risks of infection or injury.
- At-Home Use: If used at home, it is crucial to maintain strict hygiene by sterilizing the roller before and after use, avoid excessive pressure, and not overuse it (typically once every 3-4 weeks).
- Scalp Sensitivity: The scalp may be more sensitive than facial skin, so users should start with shorter needles and gradually move to 1.5mm only if comfortable and recommended.
- Consult a Dermatologist: Always consult a healthcare provider before beginning treatment to ensure it fits your scalp condition and hair loss cause.
Benefits for Hair Regrowth
- Stimulates collagen production and blood flow to hair follicles.
- Enhances absorption of topical hair growth treatments (like minoxidil).
- May reactivate dormant hair follicles with consistent use.
Conclusion
A 1.5mm derma roller can be effective for hair regrowth but requires careful use, preferably under professional guidance. For beginners, starting with shorter needle lengths and following hygiene protocols is vital to avoid side effects.
