From retinoids to exosomes, from biotin to PRP: popular skin and hair claims graded Strong, Moderate, Limited or Insufficient, each linked to the full article.

Low-dose oral minoxidil is a blood pressure medicine used off-label for hair loss; in randomised trials its effect was close to topical minoxidil. Unwanted hair growth is the most common side effect, and medical assessment with blood pressure and pulse monitoring is needed.

Oral JAK inhibitors bring back most of the scalp hair in roughly a quarter to two-fifths of people with severe alopecia areata; when the medicine is stopped, hair loss usually returns. Who qualifies, the evidence, regrowth signs and safety tests.

Exosomes are the most talked-about regenerative treatment in aesthetics. How strong is the evidence, what is the regulatory status, and what are the risks?

PRP for hair loss explained honestly by a dermatologist: which diagnoses respond, the session protocol, realistic results and when PRP is a waste of money.

Studies show modest improvements in hydration and elasticity - with big caveats: industry funding, small effects. Where your money works harder, honestly ranked.

Rapid weight loss melts facial fat too: hollow cheeks, sagging, a tired look. What Ozempic face is and which treatments genuinely help - by a dermatologist.

Polynucleotide injectables like Rejuran are trending worldwide. What the evidence actually shows, who benefits, and what remains marketing - honestly.

Same family, very different strength: tretinoin is prescription and works directly; retinol converts in the skin. Which one you need and how to start safely.

Biotin only helps if you're deficient - and deficiency is rare. Worse, high doses can distort thyroid and cardiac lab tests. The right hair loss workup instead.
