Biotin is vitamin B7, but hair loss and brittle nails do not establish deficiency. Without confirmed deficiency, there is insufficient evidence to promise thicker hair from a supplement. Discuss sudden or persistent changes with a clinician.
An important detail before blood tests
Supplemental biotin can interfere with some laboratory tests, including certain hormone and cardiac tests. Tell the clinician and laboratory the exact product, amount and time of your last dose. Do not decide on a universal two day pause yourself; the procedure depends on the test and circumstances.
Do not delay emergency care because of a supplement. Tell the team immediately what you take. Add up biotin across hair products, multivitamins and other combinations.
Simple nail care
For dry, intact skin around a nail, Aloe Vera Gelly can be a cosmetic option according to its label. It does not establish nail growth or replace biotin. Gloves for wet work and gentle handling are a more useful starting point than independently taking high doses.
Before blood tests, check hair, skin and nail supplements, including products you do not think of as vitamins. Record biotin, the daily amount and last dose time, and tell the laboratory and clinician. Do not choose a universal break from internet advice; it depends on the test and circumstances. For urgent testing, disclose what you took rather than delaying care to wait on your own.

Common questions
Is biotin risk free because it is a vitamin?
No. It can interfere with important laboratory results.
How much should I take for thicker hair?
Do not start a therapeutic dose for that goal; assess the cause of the change first.
Before first use
Choose products for your dietary routine and care needs. Follow a healthcare professional’s advice for diagnosis and treatment of symptoms. Check suitability first during pregnancy and for use by children.
