How Often Should You Use A Derma Roller For Hair Growth?

How often to use a derma roller for hair growth depends on the needle size used and the severity of your scalp condition. The derma roller schedule recommended by experts typically ranges from once a week to once a month, based on the healing time required after each session.

If you’re looking for sound advice on how many times to use a derma roller in a week or the appropriate derma roller schedule, we suggest you continue reading this article.

What is a derma roller?

A derma roller is a handheld device that creates controlled micro-injuries to your scalp. This handheld tool can be rolled over your scalp either at home or in a clinical setting. It features a rolling surface with multiple microneedles, each 0.25 mm to 1.5 mm in size.

What does a derma roller do for hair growth?

Hair growth requires a steady blood supply and a healthy collagen structure. A derma roller opens up these channels, improving blood circulation and stimulating hair growth.

Furthermore, it enhances the absorption of topicals like minoxidil, which you should ideally apply 24 hours after derma rolling to prevent systemic absorption and reduce the risk of side effects such as dizziness, sudden drops in blood pressure, and palpitations. Derma rolling further boosts hair growth when used in combination with topical minoxidil.

Why frequency matters when using a derma roller

The frequency of use usually determines the success of derma rolling treatment. During every derma rolling session, the needles puncture your scalp and cause controlled micro-injuries. The scalp takes time to heal from this because it goes through three phases: inflammation, proliferation, and remodelling.

Using a derma roller daily may hinder your body’s natural wound healing process. Visit a trusted dermatologist who can monitor such reactions and recommend the frequency of derma rolling accordingly.

Derma roller schedule recommended by expert dermatologists

The frequency of derma rolling varies significantly based on the needle size. Refer to the following table for an effective derma roller schedule:

Needle dimension	Recommended frequency	Used for	Recovery period
0.25 mm	1-2 times a week	Absorption of topicals such as minoxidil	24-48 hours
0.5 mm	Once every 10-14 days	Boost the follicles in the early hair thinning stage	3-5 days
1.0 mm	Once every 3-4 weeks under medical supervision	Effective for moderate hair loss	7-10 days
1.5 mm	As advised by your dermatologist	Used in clinical settings for dealing with extreme hair conditions	2+ weeks

With consistent use, you may experience significant improvement on your scalp. But be mindful of when to stop the derma rolling treatment, as overuse may lead to potential side effects.

When to stop using a derma roller

You may see visible results if you’re derma rolling consistently for at least 3 months. However, you should stop using a derma roller immediately if you see the following:

Extreme reactions on your scalp, such as severe irritation, prolonged bleeding and infection
Persistent side effects
Signs that your scalp isn’t responding well

When not to use a derma roller?

Derma roller should be used with caution and ideally under medical supervision. However, you should avoid using it altogether if you suffer from certain conditions. Here’s when you should avoid using a derma roller:

Active scalp infections
Psoriasis
Folliculitis
Bleeding disorders
Keloid-prone skin

For witnessing the best results on your scalp, knowing how often to use a derma roller for hair growth is critical. Results may vary, but do consider visiting a dermatologist before using a derma roller.
