It’s in every multivitamin, but does Zinc actually help with hair loss? Here’s the deal:

✅ Potent inhibitor of 5-alpha reductase (blocks DHT production)

✅ Essential for Keratin protein synthesis (the stuff hair is made of)

✅ Accelerates hair follicle recovery

Sounds good — but does it actually work?

What does Zinc really do for your hair?

Most people think of immune systems, but your hair follicles are some of the most metabolically active cells in your body. They crave Zinc.

✔ Stops DHT at the source
Zinc acts as a 5-alpha reductase inhibitor. This is the enzyme that turns testosterone into DHT. No enzyme = less hair loss. (Stamatiadis et al., 1988)

✔ Builds the structure
Your hair is almost entirely protein (Keratin). Zinc is a required cofactor for the enzymes that build this protein. Without it, hair becomes weak, thin, and breaks easily.

✔ Anti-Inflammatory Action
Scalp inflammation (micro-inflammation) is a key driver of fibrosis and permanent baldness. Zinc calms the scalp environment.

What does the science say?

📌 1988 – The Mechanism Study

A classic study in the British Journal of Dermatology (Stamatiadis et al.) looked at how Zinc affects the production of DHT in human skin.

The result: Zinc was found to be a potent inhibitor of 5-alpha reductase activity when combined with Vitamin B6 and Azaleic Acid. Vitamin B6 is also included in our KÁDESO Grow Serum.

📌 2013 – The Deficiency Connection
A study analyzed the Zinc levels in 312 patients with hair loss (Alopecia Areata and Telogen Effluvium).

The finding: Patients with hair loss had significantly lower Zinc concentrations than the healthy control group. Supplementing Zinc helped regrow hair in a significant portion of patients.

How should you actually use it?

Just popping pills? Maybe, but be careful.
High doses of oral Zinc can block the absorption of other minerals (like Copper) and cause toxicity.

What does work?

👉 Topical Delivery:
Delivering Zinc directly to the follicle bypasses the digestive system and puts the "DHT blocker" exactly where the battle is happening.

👉 Combine with Copper:
Since Zinc and Copper compete for absorption in the body, using them together in a balanced topical formula ensures you get the benefits of both without the imbalance.

Verdict: does Zinc work?

✅ Yes. It is a fundamental building block. You cannot build a house without bricks, and you cannot build hair without Zinc.

Our take?
Zinc is non-negotiable. Whether it's stopping the enzymatic conversion of DHT or physically building the hair shaft, your follicles need it.

However, it works best as part of a team. It supports the heavy lifters (like Caffeine and Copper Peptides) by ensuring the hair has the raw materials to grow.

💡 Pro tip: We formulated the KÁDESO Grow Serum with a precise balance of Zinc to ensure your follicles have the "fuel" they need to respond to the growth stimulation.
