The Short Answer: Biotin (Vitamin B7) does not typically "regrow" hair on a bald scalp, but it is critical for preventing hair loss. Biotin's primary role is to strengthen the keratin infrastructure of the hair shaft. This stops existing hair from becoming brittle and snapping off, which results in thicker-looking density, even if new follicles aren't being created.
Why Biotin Alone Isn't Enough
Many Canadians buy cheap Biotin pills expecting a miracle cure. The problem is that Biotin only addresses structure, not the growth cycle.
- What Biotin Do: Hardens the hair shaft (like armor) so it grows longer without breaking.
- What Biotin Won't Do: It cannot block DHT or wake up a dormant follicle.
The "Synergy" Approach: For real regrowth, you need more than just Biotin. Viviscal PRO combines Biotin with AminoMar™ (Marine Protein) and Apple Extract. The Biotin protects the hair, while the Marine Protein feeds the root to restart growth.
Common Vitamin Questions
Can too much Biotin cause acne?
Yes. High doses of Biotin (over 5,000 mcg) can compete with Vitamin B5 for absorption, potentially leading to cystic acne. This is why balanced supplements like Viviscal are often preferred over pure high-dose Biotin mega-doses.
Does Biotin affect lab tests?
Yes. High levels of Biotin in the blood can interfere with Thyroid and Troponin (heart) lab tests, leading to false results. Always tell your doctor if you are taking hair supplements before a blood test.
