Skin and Hair Abnormalities of Cantu Syndrome: A Congenital Hypertrichosis Due to a Genetic Alteration Mimicking the Pharmacological Effect of Minoxidil

Oral minoxidil is seen as more effective and convenient than topical minoxidil for hair regrowth, but it may cause heart-related risks. Users often combine it with finasteride or dutasteride, though some prefer topical treatments due to safety concerns.

Oral minoxidil is effective for hair loss but can cause cardiovascular side effects, such as pericardial effusion, especially in those with genetic predispositions. Starting with low doses and monitoring cardiovascular health are advised to reduce risks.

Oral Minoxidil works better for those with low SULT1A1 enzyme activity, while topical Minoxidil may be more effective for others. Some users report better results with topical Minoxidil, suggesting individual responses vary.

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.
