In today's modern world, hair loss is a widespread concern for many people, regardless of gender and age. Fortunately, there are many different treatments available that can help stimulate hair growth and restore hair to its former strength and density. One of these treatments is the use of a dermaroller. In this blog post, we'll dive into how a dermaroller works to promote hair growth and what you need to know before you jump into this treatment method.

    What are dermarollers for hair?

    A hair dermaroller is a small handheld tool used to stimulate hair growth and improve hair quality and density. It consists of a small roll with hundreds of fine needles embedded in it. When the dermaroller is rolled over the scalp, the needles create small microtraumas in the skin, which stimulates blood circulation and promotes the production of collagen and other growth factors. This can lead to increased hair growth and improved overall hair condition.

    The dermaroller can be used at home or by professionals in clinics. It is important to choose a dermaroller with needles of the appropriate length, as needles that are too long can be painful and needles that are too short may not give optimal effect. It is also recommended to consult a doctor or an expert before starting treatment, as there may be individual factors that affect the effectiveness or suitability of dermaroller treatment.

    How does a dermaroller for hair work?

    A dermaroller for hair is an effective tool to stimulate hair growth and improve hair health. It consists of a small hand-held device with microneedles of various lengths that are gently rolled over the scalp. The small needles create small microscopic wounds in the skin, which stimulates blood circulation and promotes the production of collagen and elastin in the scalp.

    When used regularly, the dermaroller can help increase the absorption of hair care products and improve the penetration of nutrients into the hair follicles. This can result in thicker and stronger hair, as well as reduce hair loss and promote hair growth. The dermaroller can also be beneficial for people who suffer from scalp problems such as dandruff or dryness.

    To use a dermaroller for hair properly, you must first ensure that both the scalp and the dermaroller are clean. Gently roll the dermaroller back and forth over the scalp in vertical, horizontal and diagonal motions. Apply light pressure and avoid rolling too hard as this can cause discomfort and irritation. After use, you can apply a soothing or nourishing hair oil or serum to maximize the effect of the treatment.

    What do you need to know before using a dermaroller for hair?

    Before you start using a dermaroller for your hair, there are some important things you should be aware of:

    1. Hygiene: Always make sure to clean both the scalp and the dermaroller thoroughly before using it. This prevents bacteria from coming into contact with the skin and reduces the risk of infection or irritation.

    2. Needle length: Choose a dermaroller with needles of the appropriate length. In general, it is recommended to use needles between 0.2 mm and 0.5 mm for hair growth treatments at home. If you are unsure, you can always consult an expert for advice.

    3. Consultation: Before starting treatment with a dermaroller, it is always a good idea to consult a doctor or an expert. They can assess the condition of your scalp and advise you on whether dermaroller treatment is suitable for you. They can also help you choose the right dermaroller and give you instructions on how to use it properly.

    4. Patience: Dermaroller treatment requires patience and consistency. It usually takes time before you start seeing results as hair has a slow growth cycle. It is recommended to use the dermaroller regularly for at least 3-6 months to achieve the best results.

    5. Caution in case of injuries or diseases: If you have wounds, infections, or other skin problems on the scalp, you should avoid using a dermaroller. The same applies if you suffer from a skin disease such as psoriasis or eczema. In these cases, it is best to consult a doctor first.

    6. Post-treatment: After using the dermaroller for the hair, it is important to give your scalp and hair the right post-treatment. You can use a soothing or nourishing hair oil or serum to soothe the scalp and add moisture to the hair. This helps to maximize the effect of the treatment and keep the hair and scalp healthy and nourished.

    How to use a dermaroller for hair

    We've created a step-by-step guide to using a dermaroller to promote hair growth:

    1. Choose the right size dermaroller: For hair growth, it is usually recommended to use a dermaroller with needles of 0.25 to 0.5 millimetres in length. These needle lengths are sufficient to stimulate blood circulation and increase the effectiveness of hair growth products without causing discomfort.
    2. Cleanse your scalp: Before using the dermaroller, make sure your scalp is clean and free of dirt, oil and product residue. You can wash your hair with a mild shampoo and let it dry completely before proceeding.
    3. Apply hair growth serum or oil: Apply a thin layer of your favourite hair growth serum or oil to a clean and dry scalp. This can be a product that contains ingredients such as minoxidil, peptides or natural oils known to promote hair growth.
    4. Roll the dermaroller over the scalp: Divide your hair into sections to ensure even coverage of the scalp. Then gently roll the dermaroller back and forth over each section of the scalp with light pressure. Make sure to cover the entire scalp without rolling too hard or too often on the same area to avoid irritation.
    5. Clean the dermaroller: After use, clean your dermaroller thoroughly by rinsing it in warm, soapy water and then disinfecting it with an alcohol-based solution to prevent bacterial growth.

    How often should you use a dermaroller for your hair?

    A dermaroller is an effective tool to stimulate hair growth and improve the condition of the hair. But how often should you actually use a dermaroller on your hair to achieve the best results?

    It is generally recommended to use a dermaroller for the hair once a week. This gives the scalp enough time to heal and regenerate between each treatment. By giving the scalp time to rest, you avoid irritation and overstimulation, which can be harmful to the hair.

    Scientific evidence for dermarollers on the hair

    The effectiveness of dermarolling for hair growth is a subject that is still under research, and there are not many scientific studies that have specifically examined the effectiveness of this method. Therefore, there is insufficient scientific evidence to conclude whether dermarolling is a reliable treatment for hair growth.

    However, there are some theories and mechanisms that can explain why dermarolling can have a positive effect on hair growth. The needles on the dermaroller create small microchannels in the skin, which can stimulate blood circulation and promote the production of growth factors and collagen. This can potentially improve the supply of nutrients and oxygen to the hair root and thus promote hair growth.

    In addition, several studies have shown that dermarolling can be effective in increasing the absorption of topical medications, such as minoxidil, used to treat hair loss. By combining dermarolling with the use of these medications, it may be possible to improve their effectiveness and results. However, it is important to note that these theories and findings are based on few studies and further research is needed to confirm their validity.

    Can I use some products in combination with dermarollers?

    Yuaia Haircare's Grow and Glow serum is an excellent choice to use in combination with a hair dermaroller, especially because of the ingredient Capilia Longa. Here are some of the reasons why this serum can be an effective and beneficial addition to your dermarolling routine:

    1. Capilia Longa's properties:

    - Capilia Longa, also known as turmeric extract, is known for its many health benefits, including its potential to promote hair growth.

    - Studies have shown that Capilia Longa can help stimulate hair follicles, which can lead to increased hair growth.

    - This ingredient has also been shown to have anti-inflammatory properties, which can help soothe and soothe the scalp, especially after dermaroller treatments.

    2. Synergistic effect:

    - By combining dermarolling with the use of a serum containing Capilia Longa, you can potentially enhance the positive effects and results of both treatments.
