Glossary Chromosome

long DNA molecule with part or all of genetic material

A chromosome is a long, thread-like structure made of DNA and proteins that carries genetic information. In humans, each cell typically contains 46 chromosomes, which are organized into 23 pairs. These structures are crucial for the proper distribution of genetic material during cell division and play a key role in heredity and the functioning of an organism.

community Chromosome 20’s balding effects and why fin likely isn’t working for some.

in Treatment 96 upvotes 1 year ago

Finasteride is effective for DHT/AR-driven hair loss but not for chromosome 20-driven cases, where treatments like minoxidil, prostaglandin analogs, and low-level laser therapy may be more beneficial. Genetic testing can help determine the underlying cause of hair loss to tailor treatment effectively.

community Why Is No One Talking About Chromosome 20?

in Chat 32 upvotes 1 year ago

Some hair loss may be linked to chromosome 20, which isn't affected by DHT blockers like finasteride. Treatments like minoxidil, microneedling, and genetic testing are suggested, but their effectiveness for this type of hair loss is uncertain.
