5 / 1000+ resultscommunity Microneedling depth. Does one length fit all areas of the scalp? Maybe not.
Microneedling depth should be customized based on hair type and scalp area, with many users finding 0.5-0.6mm effective for miniaturized hairs to avoid damage. Users report varying pain levels and results, with some preferring shorter needle lengths and others using longer ones like 1.75mm for scalp health and density improvement.
community Thin spot isn't so thin anymore, but it's getting bigger. Is this a thing?
A user is concerned about a growing thin spot on their boyfriend's head despite using Rogaine, Vitamin K, Vitamin E, Biotin, and Ubiquinol. Another user suggests starting finasteride, minoxidil, and dermarolling for better results.
community "When comparing 5% minoxidil with 0.60 mm or 1.20 mm needle lengths, Faghihi et al. found that 0.60 mm needle lengths led to significant hair count and diameter increases versus 5% minoxidil, whereas 1.20 mm needle lengths only saw hair count increases versus 5% minoxidil"
Microneedling with 0.6 mm needles combined with 5% minoxidil is more effective for hair count and thickness than minoxidil alone or with 1.2 mm needles. Biweekly microneedling at 0.6 mm depth is recommended for better results in treating androgenetic alopecia.
community Diffuse thinner - How to cosmetically increase the thickness of your hair strands themselves when you don't have bald spots?
To increase hair density appearance, options include using hair fibers, volume powders, scalp micropigmentation, and a combination of sea salt and holding sprays. Tape-in extensions and clip-in fringes are also considered, but cost and maintenance are concerns.
community M33: Is My Cowlick Actually Diffuse Thinning Despite Minoxidil?
The user is concerned about potential hair thinning and has been using minoxidil and finasteride for a year, noticing some new hair growth. They recently started microneedling to improve minoxidil absorption and seek advice on applying it to the crown area.
