Microneedling for Hair Loss

Summary

In this episode, the hosts discuss the popular topic of micro-needling, emphasizing its benefits for hair growth through collagen stimulation. They explore how micro-needling can be supercharged by combining it with topical treatments like minoxidil, peptides, and finasteride to enhance absorption and efficacy. Caution is advised against overuse and skin irritation, and the potential of newer therapies, such as oral transmucosal films, is also highlighted. The episode provides insights into effective at-home hair care methods while addressing safety concerns and the importance of informed decision-making in treatment combinations.

Takeaways

• 😀 Micro-needling is an effective hair restoration treatment that works by creating tiny pockets of damage in the skin to stimulate collagen synthesis and growth factors.
• 😀 Combining micro-needling with minoxidil can enhance its effects by increasing the penetration of the medication into the skin.
• 😀 The timing of applying minoxidil is crucial; it should be applied before micro-needling to maximize absorption, not afterward.
• 😀 Peptides and exosomes are newer topical therapies that can be used with micro-needling to add extra growth factors and further stimulate hair regrowth.
• 😀 Overuse of micro-needling (e.g., more than once a week) can cause micro scarring and other adverse effects on the scalp, so it should be done with caution.
• 😀 Minoxidil’s effectiveness can be increased by using micro-needling, as it helps to overcome the limitation of its 5% solution, which is difficult to stabilize in higher concentrations.
• 😀 Retinoic acid is sometimes added to topical therapies for better absorption, but it can be photosensitizing and cause skin irritation in some individuals.
• 😀 Plant-based exosomes have fewer regulatory restrictions than human-based ones, which are strictly controlled due to safety concerns around bloodborne diseases.
• 😀 Topical finasteride is an option for patients seeking to reduce side effects from oral finasteride, and can be effectively combined with micro-needling for better scalp absorption.
• 😀 Transmucosal films (OTFs) are a newer way of delivering medications without passing through the digestive system, potentially offering better absorption and fewer systemic side effects.

Q & A

What is micro-needling and how does it help with hair regrowth?

Micro-needling is a treatment that involves creating tiny channels or 'micro-injuries' in the skin using a needle device. This stimulates the skin's natural healing process, promoting collagen production and growth factors, which can enhance hair growth and improve scalp health.

Why is micro-needling considered an effective treatment for hair loss?

Micro-needling is effective because it stimulates the skin at a deeper level, encouraging the body to produce collagen and growth factors. These biological responses help rejuvenate the scalp and improve the environment for hair growth, benefiting both existing and newly growing hair follicles.

Can micro-needling be done at home, and what are the benefits of doing it at home?

Yes, micro-needling can be done at home with a dermaroller or microneedling device. It offers convenience, cost-effectiveness, and gives individuals control over the frequency and intensity of the treatment, which may appeal to those who prefer not to take oral medications.

What is the recommended frequency for micro-needling treatments, and why should it be limited?

It is generally recommended to do micro-needling once a week. Overuse can lead to micro-scarring or skin damage. Too frequent use may also cause irritation, so it's important to allow the scalp time to heal between sessions.

What should be considered when combining micro-needling with minoxidil?

When combining micro-needling with minoxidil, it's important to apply minoxidil before micro-needling, as the tiny channels created by the needling will enhance the absorption of minoxidil. However, the skin may be more sensitive after micro-needling, so applying it immediately after may cause stinging or irritation.

What are peptides and exosomes, and how can they enhance the effects of micro-needling?

Peptides and exosomes are compounds filled with growth factors that can promote tissue regeneration and healing. When used topically on the scalp after micro-needling, they can work synergistically with the body's natural growth factors, amplifying the hair regrowth process.

Are there any risks associated with combining micro-needling with peptides or exosomes?

While combining micro-needling with peptides or exosomes can enhance hair regrowth, it's essential to avoid overuse of micro-needling, as it may cause skin irritation or micro-scarring. Additionally, the long-term effectiveness of combining these treatments is still being studied, and care should be taken not to damage the scalp.

What are the advantages of using topical finasteride with micro-needling?

Topical finasteride can be used with micro-needling to target hair loss while minimizing systemic side effects that may occur with oral finasteride. Micro-needling can help improve the penetration of the medication into the scalp, making it more effective.

What is the role of oral transmucosal films (OTFs) in hair restoration treatments?

Oral transmucosal films (OTFs) are a newer form of medication that dissolves in the mouth and bypasses the digestive system, leading to better absorption into the bloodstream. This method allows medications like finasteride or minoxidil to reach the scalp more effectively, potentially reducing systemic side effects.

Why should caution be exercised when using retinoic acid with micro-needling?

Retinoic acid can be a powerful ingredient in promoting skin renewal, but it can also cause skin irritation, particularly when used with micro-needling. It can make the skin more sensitive to the sun, leading to an increased risk of sunburn, so it's essential to use it cautiously and apply sunscreen afterward.
