Clinical studies have indicated that the optimal needle depth for microneedling is typically 1.5mm. This depth allows the needles to penetrate the dermis, accessing a greater supply of blood capillaries, which triggers a potent inflammatory response.
A size of 0.5mm can enhance the absorption of topical treatments if you are doing some regular hair growth serum treatment. In comparison, 1.0mm to 1.5mm can be used if you intend to stimulate more deep scalp layers, promoting hair growth with the microneedling treatment.
For scalp microneedling, you often see needle lengths of 0.5mm to 1.5mm, although you should leave the longer lengths to the professionals. 0.5mm is a good starting point for scalp microneedling at home when done carefully.
When microneedling, we use different depths depending on the skin type, and the part of the face we are treating. For example, the skin on your forehead is much thinner than the skin on your cheeks---thus we would start at about . 5 mm and maybe go as deep as 2.5 mm over the cheeks or deep scars.
Needles measuring 0.6mm may be the most effective size for treating hair loss [4]. While 0.6mm isn't a common commercial size, 0.5mm derma rollers are widely available. So this is a good place to start if you haven't used a home derma roller or derma stamp before.
We also demonstrated that among various lengths and cycles of microneedle stimulation, 0.25 mm/10 cycles and 0.5 mm/10 cycles showed the best results. From our results, we suggested that microneedle stimulation itself could induce hair growth via Wnt/β-catenin signaling and VEGF.
In clinical studies, needle lengths of 0.6mm to 2.5mm (used once weekly or bi-weekly) have been shown to improve hair counts in men with androgenic alopecia (AGA). Even still, there's debate over whether shorter needle lengths (used more frequently) might lead to better results.
Improper Technique: Applying excessive pressure or using incorrect needle depth can lead to skin trauma, scarring, and permanent damage. Infection Risks: Poor hygiene practices, unsterile equipment, or microneedling over active lesions increase the chances of bacterial, viral, or fungal infections.
Unlock the secret to hair regrowth with microneedling, as supported by compelling evidence. Studies have confirmed that undergoing microneedling sessions every 1–3 weeks can promote hair regrowth.
Derma Rollers with a needle length of 0.25mm is usually considered enough to stimulate mild blood circulation to the beard area, but to reach the follicles and to enhance the collagen production, you should opt for 0.5mm needle length. Anything over or under is not recommended for targeting beard growth.
The Dr. Pen 24-pin and 36-pin microneedling cartridges are the best needles for collagen and elastin production, and stimulating dormant hair follicles in the scalp. This is essential for hair follicles to enter the growth phase.
Antibody anticytokeratin (CK), 15 was used as a bulge stem cell marker. Results: The mean length of a scalp hair follicle is 4.16 mm. The infundibulum measures 0.76 mm, the isthmus 0.89 mm, and the inferior portion 2.5 mm. The insertion of the arrector pili muscle is located 1.65 mm deep.
Microneedle your scalp 5-7 times vertically. Lift roller and microneedle 5-7 times horizontally. Apply light pressure. Combine with hair growth serum for more effective results.
The correct depth for microneedling stretchmarks is 1.5mm-2.5mm. It's recommended to start with a 1.5mm depth for 3-4 sessions before considering a larger size. Deep dark stretch marks usually take 3-5 sessions of a 2mm+ needle depth to see results.
In short, a microneedling session looks to increase hair growth by stimulating blood flow to the scalp. When doing so, microneedling is effective at treating hair loss and thinning hair. In some cases, it can even promote hair regrowth. Creating tiny wounds, the micro needles stimulate blood flow on the scalp.
Moisturizers to Use: Use lightweight, non-greasy moisturizers or serums designed for sensitive or healing scalps. Your hair clinic may provide or recommend products specifically formulated for post-microneedling care.
Myth: sun is the enemy of microneedling!
This is why we'd never recommend microneedling during the day. To keep your skin happy and healthy, always microneedle in the evening – this means your skin has the whole night to restore itself, and you can wake up to sensational skin.
In the Microneedling group, 41 (82%) patients versus only 2 (4.5%) patients in the Minoxidil group reported more than 50% improvement [Table 3].
Clinical studies have indicated that the optimal needle depth for microneedling is typically 1.5mm. This depth allows the needles to penetrate the dermis, accessing a greater supply of blood capillaries, which triggers a potent inflammatory response.
Shallow microneedling is suitable for minor issues and overall skin enhancement, while medium and deep microneedling is more effective for addressing moderate to severe skin concerns.
How often should I use a 1.5 mm derma roller on the scalp? For most individuals using a 1.5 mm derma roller on the scalp for hair growth purposes, it is generally recommended to perform the microneedling treatment once every 4 to 6 weeks.
For treating acne and other scars as a routine, a needle length of 1.5–2 mm is usually used. When microneedling is used as a procedure to treat ageing skin and wrinkles, the needle length of 0.5 mm or 1.0 mm is usually recommended.
