Evidence based microneedling on scalp for hair loss? (Photo)

Question

32M with B/G of seborrheic dermatitis 1/52 in remission presents with androgenetic alopecia. 10/7 ago started 1mg finesteride and 1mg oral minoxidil. Taking viviscal hair supplement and viviscal hair oil for thinning hair. There are conflicting evidence in research regarding microneedling for hair loss. What is your experience on microneedling alone (without PRP or topical minoxidil). What needle length and how often would you recommend? Thank you

Hello !

There is limited research on the effectiveness of microneedling alone for treating androgenetic alopecia, and the results are mixed. Some studies suggest that microneedling can help improve hair density and thickness, while others show no significant difference compared to a control group.

In terms of needle length, studies have used different lengths ranging from 0.25 mm to 1.5 mm. The ideal length may depend on factors such as the individual's skin thickness and hair loss severity. Generally, shorter needles are used for more superficial treatments, while longer needles are used for deeper penetration.

As for frequency, most studies have used weekly or biweekly treatments for several months, with some showing improvement after 12 weeks of treatment.

Overall, microneedling alone may be a less effective treatment option compared to other therapies such as finasteride and minoxidil. However, it may be a worthwhile addition to a comprehensive treatment plan for some individuals.

It is important to consult with a dermatologist or hair loss specialist to determine the best treatment plan for your specific case, as well as to discuss any potential risks or side effects of microneedling.

Best of luck !
