Bullsh*t or not?

Let’s find out. We’re checking every claim, one by one.

The supplement industry loves this one. It's in every gummy bear and "hair pill" on earth. Here’s why:

✅ Essential cofactor for producing Keratin (hair protein)

✅ Increases hair elasticity and strength

✅ Prevents hair from becoming brittle and snapping off

Sounds good — but does it actually work?

What does Biotin really do for your hair?

Biotin (Vitamin B7) isn't a growth stimulant like Minoxidil; it is a structural builder.

✔ Builds the Infrastructure
Your hair is made of Keratin. Biotin is the "worker" that helps enzymes build this protein. Without it, the construction site shuts down.

✔ Metabolizes Fatty Acids
Biotin is crucial for breaking down fats and amino acids. This process creates the protective oil barrier on your scalp that keeps hair hydrated.

✔ Stops Breakage
Many people think they have "hair loss" when they actually have "hair breakage." Biotin strengthens the shaft so it doesn't snap before it gets long.

What does the science say?

📌 2017 – The Reality Check (Review)

A comprehensive review (Patel et al.) analyzed 18 reported cases of Biotin use for hair loss.

The Truth: Biotin shows massive improvements in hair growth IF you have a deficiency or a hair pathology (like uncombable hair syndrome).

However, for perfectly healthy people with high Biotin levels, adding more Biotin didn't act as a magic growth multiplier. It restores health, it doesn't force growth beyond your genetic limit.

📌 2016 – The Deficiency Connection
So, do you need it? A study by Dr. Ralph Trüeb analyzed 541 women complaining of hair loss.

The finding: 38% of women complaining of hair loss were deficient in Biotin.

This suggests that while it's not a magic cure for everyone, a significant portion of people losing hair are indeed lacking this vitamin, making supplementation critical for them.

How should you actually use it?

Taking massive doses (10,000% DV)? Careful.
Extremely high oral doses can interfere with lab tests (like thyroid and troponin tests), leading to misdiagnoses.

What does work?

👉 Balanced Intake:
You don't need mega-doses. You need a consistent, adequate supply to ensure your keratin production never halts.

👉 Topical Support:
Using Biotin in a scalp serum can help improve the texture and quality of the hair strand directly without messing with your blood work.

Verdict: does Biotin work?

✅ Yes, but with a caveat. It is not a growth stimulant; it is a deficiency corrector.

Our take?
Think of Biotin as the "safety net." It ensures your hair is strong enough to grow without breaking. If you are deficient (which 38% of hair loss patients are), it is a game changer.

However, relying only on Biotin is a mistake. It strengthens the hair, but it doesn't block DHT.

💡 Pro tip: We include Biotin in the KÁDESO Grow Serum to strengthen the hair shaft, while ingredients like Caffeine and Saw Palmetto do the heavy lifting of stimulating growth.
