Whether you’re losing hair or just aiming for fuller, denser hair, a product with Redensyl can be a game-changer.

If you don’t know about this compound, Redensyl is considered one of the most potent hair growth stimulators. Instead of targeting a specific cause, it addresses the entire hair growth process. As a result, Redensyl not only minimizes hair shedding but also enhances hair volume, density, and thickness. What sets it apart is its solid scientific backing, earning the trust of experts and myself alike. Ready to incorporate this potent ingredient into your haircare routine? Below, we share the best Redensyl products for hair growth. But first, let’s find out what Redensyl is and how it makes your hair grow faster and thicker

What is Redensyl?

Redensyl is a haircare ingredient made by Induchem Companies. More precisely, it’s a mix of four active ingredients: dihydroquercetin-glucoside (DHQG), epigallocatechin gallate-glucoside (EGCG2), glycine, and zinc. I know it sounds like a chemistry class, but the purpose of this mix is quite simple: to help your hair grow healthier and minimize hair shedding.

Zinc is a mineral that acts as a building block for your hair, making each strand stronger from the inside. DHQG is a stimulator for the tiny cells in the roots of your hair. These cells are vital as they initiate hair production. When DHQG comes into play, it’s like it’s telling these cells to move the hair from the resting stage to the growing stage. This is what makes your hair start growing. EGCG2 is another key player. It fights off things that can cause damage or inflammation to your hair follicles. Both DHQG and EGCG2 are natural ingredients called polyphenols. You can find them in things like green tea or the wood of a tree called Larix europaea. That’s why, when you look at the ingredient list of your haircare products, you might see green tea or this tree mentioned, along with zinc—this is basically Redensyl.

How Redensyl works

During a lifetime, the hair passes through four stages: anagen, catagen, telogen, and exogen. The anagen phase is where your hair actively grows and can last from 2 to 7 years. While you age, or for health reasons, the duration of the anagen stage can decrease. This makes the hair weaker and grows slower than usual. At the end of the anagen phase, the hair enters the catagen phase, a transition to the telogen stage during which the follicles rest. In this stage, while the existing hair is resting, new hair grows.

What Redensyl does is move the hair follicles from the telogen phase to the anagen. Clinical studies have shown that Redensyl can increase the percentage of hairs in the anagen and decrease the hair count in the telogen phase. During one research, using a Redensyl-infused product increased hair density by 17%, with a total of 20,000 new hairs after three months.

Together, these ingredients can pump up your hair’s thickness by up to 13%.
