Microneedling at home, step by step

Read microneedling for hair loss first for what the trials show and who should not do it. This guide is about doing it at home, safely and consistently.

What you need

A roller or a stamp. Rollers are cheap and common. Stamps press straight down, which some people find easier to control on the scalp and less likely to tug at hair. Choose one with stainless steel or titanium needles and a clearly stated needle length.
A disinfectant. Isopropyl alcohol of about 70% is the usual choice for cleaning the tool.
A mirror, or a second mirror to see the crown.
Clean hands and a clean towel.

Needle length

Needle length is the number on the box, in millimetres. Shorter needles are gentler; longer ones go deeper and hurt and bleed more.

The trial that made microneedling popular used a 1.5 mm roller once a week.³ But a 2025 analysis of 12 trials found that needle depth, device type and how long treatment lasted did not change the effect on hair counts.¹ For home use, that is a good reason to stay moderate. Many people use about 0.5 to 1.0 mm at home, and leave longer needles to clinics with sterile, single-use tips.

How often

Once a week is the most common schedule in trials and the most common advice.³ Your scalp needs time to heal between sessions. More often is not better, and it raises the risk of irritation and infection.

If your scalp is still red or sore when the next session is due, wait.

Step by step

Check your scalp. No cuts, spots, rash, sunburn or flare of a skin condition. If in doubt, skip this week.
Wash your hair with a mild shampoo and let it dry. Do not apply minoxidil before the session.
Clean the tool. Soak or spray the head with 70% alcohol and let it air-dry. Wash your hands.
Work in sections. Part your hair over the thinning area. With a roller, roll in one direction a few times, lift, then change direction: up and down, side to side, and diagonally. Lift the roller to change direction instead of twisting it on the skin, which can tear the skin and pull hair. With a stamp, press down, lift, move half a stamp-width, and repeat.
Use light pressure. Let the needles do the work. Pinpoint redness is expected; a little pinprick bleeding can happen with longer needles. Pain or real bleeding means you are pressing too hard.
Clean the tool again with alcohol, let it dry, and store it in its case.
Leave your scalp alone for the rest of the day: no hair products, no hat if you can avoid it, no swimming or heavy sweating.

A session usually takes five to ten minutes.

Fitting it around minoxidil

Keep using minoxidil as usual on the other days. On microneedling days, many people skip the minoxidil dose right after the session and restart the next day, once the scalp has calmed down, to avoid stinging and irritation. Trials used different timings, and there is no firm evidence on the best gap. If your scalp stings or stays red, wait longer.

Do not apply other products to a freshly needled scalp, such as essential oils, peptide serums or anything with fragrance. The tiny channels let substances deeper into the skin, which is exactly when irritation and allergic reactions are more likely.

Keeping the tool safe

Never share it. It touches broken skin and can spread infection.
Clean it every time, before and after.
Replace it when the needles feel blunt, catch on the skin, or look bent. Many people replace a roller every couple of months with weekly use; follow the maker's advice.
Store it dry in its case, away from children.

How to judge it

Microneedling trials measured results at about three to six months, alongside minoxidil.¹ Take progress photos before your first session and compare at six months. If you cannot see a difference compared with minoxidil alone, it is reasonable to stop.
