Is 1.0mm depth for PRP hair thinning/loss effective enough?

The effectiveness of PRP (Platelet-Rich Plasma) therapy for hair thinning or loss can depend on several factors, including the depth of injection. Generally, the scalp's dermal layer, where hair follicles reside, is typically reached at a depth of about 4-6mm. This is why many practitioners aim for this depth to ensure that the PRP reaches the hair follicles effectively.

Using a 1.0mm depth may not be sufficient to deliver the PRP to the follicular level, which could impact the treatment's effectiveness. However, some practitioners might use shallower depths for specific reasons, such as targeting the superficial layers for skin benefits or in cases where the scalp is very thin.

Here are a few steps you might consider:

Consult with Your Practitioner: Discuss your concerns with your nurse or the administering physician. They can explain the rationale behind using a 1.0mm depth and possibly adjust the treatment based on your feedback and treatment goals.

Seek a Second Opinion: If you're unsure about the current treatment protocol, consulting with another experienced professional in PRP for hair loss can provide additional insights and recommendations.

Consider Other Factors: PRP's effectiveness can also depend on the concentration of platelets, the frequency of treatments, and the overall health of your scalp and follicles.

Ultimately, it's important to ensure that your treatment plan is tailored to your specific needs and is based on the latest evidence-based practices.

PRP is not very effective for hair loss. I would suggest Dermapen treatment with 2.0 mm deep with exosome application to reduce the hair loss. However you might need sedation for this.
