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

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 !
