What is a derma roller?

A derma roller is a small roller covered in tiny needles ranging in length from 0.25mm to 1.5mm. When rolled over the scalp or hairline, it creates tiny punctures that can make it easier for the medicinal qualities of topicals and oils to reach the hair follicles. Think of it like aerating a lawn. Doing so helps nutrients, hydration, and sunlight reach the roots so that healthier grass can grow. Likewise, using a derma roller with topicals and oils can help increase the absorption of the products you apply afterward.

A derma roller can also stimulate cell turnover and improve scalp circulation, which provides a healthier environment for robust hair growth. The longer needle lengths (over 0.5mm) are better for stimulating cell turnover; however, the longer the needle, the higher the risk of injury. If you are interested in experiencing derma rolling with needles over 1.5mm, it is best to seek professional help and not practice this at home.

Which derma roller should I buy for hair growth?

When shopping for the right derma roller for your scalp, needle lengths of 0.25mm to 0.50mm are best. The micro-traumas they create are superficial, and you are less likely to suffer from excessive skin redness and discomfort when you stick to these lengths. Additionally, you do not have to space out your derma rolling treatments to allow healing time as you would with a 0.75mm or longer derma roller.

Know that using a derma roller does cause slight irritation, similar to shaving your legs but on a smaller scale. Therefore, the topicals or oils you choose should be non or minimally irritating, particularly if you have a sensitive scalp. Also, it is best to test your products on the inside of your elbow for a week or two before applying them to your scalp to ensure they will not cause an allergic reaction. While doing so, practice derma rolling every few days to determine how your scalp will react to it.

How to Derma Roll

When using a derma roller, start by sectioning the areas where you are experiencing hair loss. For example, if you have Androgenic Alopecia with a widening part and some diffuse thinning, you may want to make a middle part and then create 3-4 horizontal parts. Apply a few drops of oil or topicals to the parts, then massage them in. You will pass the derma roller over the parts in the direction of the hair growth 4-5 times. Apply the same amount of pressure that you would if painting a portrait. After you have finished derma rolling, apply a few more drops of oils or topicals, if desired.

To avoid infections and injuries:

  • Sanitize the derma roller before and after each use by soaking it in 70% or more isopropyl alcohol. Ensure it is completely dry before using, and do not use it on wet hair.
  • Use cotton balls to apply your oils and topicals to your scalp. Do not apply them to the derma roller.
  • If you drop the derma roller or it gets crushed or damaged in any way, discard it. Bent needles can cause injuries.
  • Replace worn derma rollers every two months.

Not all hair loss is the same, and some products that work for certain types of hair loss are ineffective for others. Additionally, topicals and oils may be ineffective for certain types of hair loss, particularly if they are caused by an autoimmune condition such as Lupus.

Minoxidil (brand name: Rogaine)

Best for: Androgenic Alopecia (also called Male or Female Pattern Thinning), hair loss due to PCOS

This is the first-line, FDA-approved treatment for thinning due to an excess of androgenic hormones. It generally presents as a widening part and diffuse thinning at the top of the head. It also tends to run in families. Minoxidil halts this hair loss and can help regrow hair in approximately six months. If you grow hair when using it, it will fall out when you stop using it. Minoxidil (or Rogaine) primarily comes in two strengths: 2% and 5%. The men’s and women’s formulations contain the same ingredients as the generic Minoxidil and the name-brand Rogaine.

So, if cost is a concern, purchasing the women’s name-brand product is unnecessary. As a curly, you may want to avoid the alcohol-based formulations. These generally contain 2% Minoxidil and require a twice-a-day application. The foam is alcohol-free, contains 5% Minoxidil, and must only be applied once a day. It can, however, cause some serious side effects, such as a racing heartbeat and skin irritation. A 2% foam alternative is DrFormulas® HairOmega® Foaming Hair Growth Serum.
