A receding hairline and thinning temples are often among the first signs of hair thinning, and they're also the most visible. Microneedling the hairline needs a slightly different technique from the rest of the scalp, because there's less hair to work through and the skin can be thinner. Here's how to do it well, and what to expect.
The short answer: microneedling can support fuller-looking hair along the hairline and temples, especially when combined with scalp products like minoxidil. Use a 24-pin cartridge at 0.6mm, glide along and just behind the hairline every 2 weeks, and give it 3 to 6 months before judging results.
Why the hairline and temples thin
Gradual thinning at the hairline and temples is very common, especially in men, and is largely down to genetics and hormones. Over time, hairs in these areas can become finer and shorter. It usually happens slowly over years. If your hairline is changing suddenly, or you have patches, itching or soreness, speak to your GP.
How microneedling helps the hairline
Scalp microneedling prompts the scalp's natural renewal processes and helps scalp products absorb more effectively. Research on combining microneedling with minoxidil is particularly encouraging. See Microneedling With Minoxidil and Microneedling for Thinning Hair.
Setting realistic expectations
- Earlier is better. Areas that still have fine hairs tend to respond better than areas that have been smooth for years.
- Results are gradual, usually over 3 to 6 months.
- Maintenance matters. Most people keep up their routine to maintain results.
Cartridge and depth
- 24-pin at 0.6mm is ideal for the hairline and temples. It's large enough for even coverage but small enough to follow the curve of the hairline.
- You can move to 0.8mm after a few comfortable sessions, but don't go beyond 1.0mm at home.
Hairline technique, step by step
- Wash and dry your hair, then push it back off your forehead with a headband or clips.
- Disinfect your hands, pen and the hairline area, and let it dry.
- Attach a new, sealed 24-pin cartridge and set 0.6mm and a low speed.
- Apply a thin layer of hyaluronic acid along the hairline and temples.
- Glide along the hairline in short, overlapping strokes, holding the pen at 90 degrees.
- Work backwards 2 to 3cm into the area behind the hairline, where hair is still present.
- For the temples, keep the skin taut and use gentle strokes, as this skin can be thinner.
- Finish with a little more hyaluronic acid.
The whole hairline takes around 5 to 10 minutes. If you're also working on the crown, see our scalp microneedling guide.
How often
Every 2 weeks at 0.6mm, or every 3 to 4 weeks at deeper settings.
Aftercare
- Wait 24 hours before washing your hair.
- Wear a hat or SPF on exposed skin along the hairline.
- Avoid hair dye and chemical treatments for a week.
- If you use minoxidil, ask your pharmacist how long to wait before applying it.
Track your progress
Hairline changes are easy to miss day to day. Take photos monthly, from the front and both sides, with your hair pushed back, in the same light. Compare month to month rather than week to week.
