When it comes to promoting hair growth and treating various hair conditions, derma rollers have gained significant popularity. These handheld devices are used to create tiny punctures in the scalp, stimulating the natural healing process of the skin and encouraging hair growth. However, not all derma rollers are the same, and the choice of needle size is a crucial factor to consider. In this article, we will explore the differences between a 1.5mm needle size and other sizes, helping you make an informed decision for your hair needs.
1. Needle Length: Depth Matters
The most crucial distinction between a 1.5mm needle size and other sizes lies in the depth of penetration into the scalp. The 1.5mm needle length is considered a longer length and can penetrate deeper into the skin compared to shorter lengths such as 0.5mm or 1mm. With deeper penetration, the 1.5mm needle size stimulates collagen production and promotes enhanced blood circulation, leading to better hair growth. However, it is essential to note that the longer needle length also increases the risk of pain and potential side effects, so it might not be suitable for everyone.
2. Targeting Specific Hair Concerns
The choice of needle size should also depend on your specific hair concerns. If you are looking to stimulate hair follicles and promote overall hair growth, a 1.5mm derma roller might be the right choice. However, if you are primarily concerned about enhancing the absorption of hair growth products, such as serums or oils, a shorter needle length like 0.5mm can suffice. It is important to assess your hair goals and choose the needle size accordingly to maximize results.
3. Pain and Discomfort Levels
Using a derma roller can cause some discomfort and pain, especially with longer needle lengths. The 1.5mm needle size may lead to more pain compared to shorter sizes due to the deeper penetration into the skin. However, the level of pain can vary from person to person, and some individuals might find it tolerable. If you have a low pain threshold or sensitive skin, it might be more suitable to opt for a shorter needle size that provides similar benefits with less discomfort.
4. Frequency of Use
Another important consideration is the frequency of derma roller usage. Longer needle sizes, like 1.5mm, are typically recommended for less frequent use, such as once every three to four weeks. This is because the deeper penetration requires more time for the skin to heal and regenerate. However, shorter needle lengths can be used more frequently, even up to once a week. Depending on your preference and schedule, you can choose a needle size that aligns with your desired frequency of usage.
5. Side Effects and Risks
Derma rolling, especially with longer needle sizes, can carry potential side effects and risks. These may include redness, bleeding, bruising, and skin irritation. It is crucial to follow proper hygiene practices, clean the roller before and after each use, and avoid sharing your derma roller with others to minimize the risk of infection. If you have any pre-existing skin conditions or concerns, it is advisable to consult a dermatologist or a healthcare professional before incorporating derma rolling into your hair care routine.
