vascular epidermal growth factor VEGF VEGF liposomes hair growth hair density hair thickness topical gel biochemical analysis hematological analysis toxicity

TLDR VEGF gel increases hair growth but may have potential toxicity.

The study evaluated the effects of a topical gel with VEGF liposomes on hair growth and its toxicological aspects in 18 hamsters. Results showed that VEGF increased hair density and follicle diameter significantly. However, biochemical and hematological analyses revealed potential toxicity, with lower red blood cell and mean corpuscular hemoglobin values, and elevated AST, ALT, and alkaline phosphatase levels in VEGF-treated animals. Despite these findings, most blood parameters showed no significant differences except for a reduction in eosinophils. The study concluded that while VEGF effectively stimulated hair growth, further research was needed to confirm its safety.

community Do you keep gains if you stop microneedling?

in Microneedling 15 upvotes 3 months ago

Stopping microneedling may result in losing hair gains, as it enhances the effectiveness of treatments like minoxidil. Combining microneedling with minoxidil and finasteride is more effective than using microneedling alone.

community Minoxidil Response Bottlenecks: Why Sulfation and Transport Matter (And Where Tretinoin Fits In)

in Research 461 upvotes 5 months ago

Minoxidil's effectiveness is limited by the need for sulfation and proper transport to hair follicles, with tretinoin potentially enhancing its effects by promoting enzyme activity and keratinocyte differentiation. Tretinoin may improve minoxidil's response by boosting the expression of necessary enzymes and transporters.
