Glossary High-Resolution Mass Spectrometry

advanced technique for precise molecular mass measurement

High-Resolution Mass Spectrometry (HRMS) is an advanced analytical technique used to precisely measure the mass of molecules. It provides highly accurate mass measurements, allowing scientists to identify and characterize complex chemical compounds, including those in biological samples like hair, with great specificity.

A 15-year-old is upset about androgenic alopecia and its effect on self-esteem. Recommendations include minoxidil, microneedling, hair systems, and focusing on self-confidence and therapy.

community Almost 20 Years on Finasteride - AMA

in Progress Pictures 837 upvotes 1 year ago

A user successfully halted hair loss using finasteride for 17 years and recently switched to dutasteride for stronger DHT suppression. They experienced no major side effects, maintained a full head of hair, and fathered three children without issues.

community The Fear of Oral Minoxidil is Overblown

272 upvotes 1 year ago

Low-dose oral minoxidil is a safe and effective hair loss treatment with fewer side effects than previously feared. Users often prefer it over topical minoxidil for better results, though some experience side effects like increased body hair and cardiovascular issues.

community Before you feel down about your hairloss

27 upvotes 9 years ago

Hair loss can be distressing, but treatments like finasteride, minoxidil, and scalp micropigmentation can help manage it. Embrace self-improvement, focus on personal goals, and maintain a positive attitude despite hair loss challenges.
