Choose to roll areas where hair is thinning, rather than the entire scalp.
“Roll gently in multiple directions (vertically, horizontally and diagonally), lifting the roller between passes rather than dragging it across the skin. This helps ensure even stimulation while minimizing unnecessary trauma to the scalp,” says Dr Jaafar. “Consistency is more important than intensity. Over-aggressive rolling can cause irritation without improving results.”
Keep the pressure light.
“The key is controlled pressure; the goal is to stimulate the scalp, not cause trauma or bleeding,” says Souza.
For strongest results, apply a targeted scalp serum to the areas you’ve derma rolled.
“The micro-channels created by the needles enhance the penetration of topical therapies such as minoxidil, peptides or growth factor serums,” says Souza. “Studies have shown that combining microneedling with minoxidil significantly increases hair count compared with using minoxidil alone.”
Keep aftercare simple.
“Avoid harsh products, heavy oils or heat styling immediately afterwards. Gentle cleansing and soothing scalp products can help support recovery,” she adds. “It is also important to allow the scalp time to recover between sessions rather than repeating treatment too frequently.”
Monitor the scalp after treatment.
“Look out for excessive redness, swelling or signs of infection afterwards,” says Souza—noting you should consult a medical professional if you have any concerns.
If you have no adverse effects, repeat based on your derma roller’s needle length.
“Frequency depends on needle length—shorter needles can be used weekly or twice weekly, while longer needles are typically used less frequently,” adds—though needles larger than 0.5mm are not advised for at-home use. “Consistency over several months is essential, as hair growth cycles are slow and visible results often take three to four months or longer.”
Who does derma rolling for hair work best for?
“Derma rolling is most appropriate for individuals with early to moderate hair thinning, particularly androgenetic alopecia in men or women, where follicles are still present but miniaturizing,” says Souza. “There is also some emerging evidence that it may support treatment of conditions like alopecia areata or telogen effluvium, although the data is less robust.”
And while micro needling can stimulate growth factors and improve circulation around hair follicles—which may help support thicker, healthier hair strands—“it tends to work best when there is an underlying thinning process rather than simply trying to boost already healthy hair,” adds Dr Jaafar.
