This study demonstrates that confocal laser scanning microscopy can effectively visualize the rapid diffusion and penetration pathway of a dye into the hair follicle in fresh human scalp skin.
Matrixyl 3000 is discussed as a potential topical treatment for hair growth, but concerns are raised about excess collagen production being a consequence of hair loss. The conversation suggests that androgen-induced miniaturization leads to hair follicle death and skin fibrosis.
Mallia Aesthetics has developed MAL-838, a hormone-free product derived from sCD83, which stimulates hair growth without disrupting the skin microbiome. sCD83 promotes hair growth by activating hair follicles and preventing cell death, offering a localized treatment without systemic side effects.
The conversation discusses using a microneedling device on the face after using it on the scalp, with suggestions to use a depth of 0.2mm for facial treatments. Caution and proper sterilization are advised due to the sensitivity of facial skin.
Microneedling depth should be customized based on hair type and scalp area, with many users finding 0.5-0.6mm effective for miniaturized hairs to avoid damage. Users report varying pain levels and results, with some preferring shorter needle lengths and others using longer ones like 1.75mm for scalp health and density improvement.
The conversation is about the safety of using a dermastamp at 0.25mm depth twice a day when applying Minoxidil. The user seeks confirmation on whether this practice is safe despite mixed opinions.
Is scalp micropigmentation suitable for people with sensitive skin?Providers say scalp micropigmentation suits most skin types and describe patch tests, hypoallergenic pigments and a skin consultation for sensitive skin. These are provider claims rather than independent safety evidence, and pigment reactions remain a risk.
