Today, we will talk about one of the most effective hair growth stimulators found in cosmetics: Redensyl. If you want to try Redensyl, here is everything you need to know about this potent hair care ingredient.  

What is Redensyl?

Redensyl is a breakthrough ingredient clinically tested to encourage hair growth and improve thickness and density. Redensyl was developed by Induchem Laboratories (Switzerland and USA). Induchem’s center came up with Redensyl after researching the hair follicles’ stem cells (HFSCs) role in the hair growth cycle. They confirmed that HFSCs have a crucial function in initiating the hair’s growth phase, thus the need for an activator of hair follicle stem cells became a primary concern for them.

What is Redensyl made of?

Redensyl is obtained from a combination of botanical ingredients and contains 0.005% Dihydroquercetin-glucoside (DHQG), 0.0009% Epigallocatechin gallate-glucoside (EGCG2), 0.005% glycine, 0.002% zinc chloride, 0.015% metabisulfite, and 50% glycerin. To understand how Redensyl works, you first need to understand the hair follicle structure and how it produces hair. We will try to explain this in very simple terms.

Hair loss and Redensyl

The hair follicle is surrounded by two main structures – the inner root sheath (IRS) and the outer root sheath (ORS). While IRS helps shape and mold the newly developing hair shaft, ORS includes a region known as the bulge, which contains epithelial stem cells responsible for regenerating follicles in the growing stage. Practically, these ORS stem cells (ORSc) have the potential to form new hairs.

Another essential structure is the dermal papilla, situated at the very bottom of the hair follicle. Dermal papilla contains blood vessels with the role of delivering nutrients to each follicle and hair shaft.

In order to grow hair, the hair follicle undergoes cycles of degeneration and regeneration due to stem cell involvement. These phases are called anagen, catagen, and telogen. At the beginning of each new anagen phase, the follicles start a regenerating process that requires a reservoir of follicle stem cells. While in the anagen phase, the hair is actually growing until it enters the catagen phase, marked by the end of the reproduction of ORS stem cells. In the telogen phase, most ORSc are in a dormant state, and the hair follicles remain inactive for about 3 months before the whole cycle repeats. Once follicle stem cells become activated, they migrate along with the ORS to the follicle base, where they produce new hair shafts.

How does Redensyl stimulate hair growth?

After years of research, the conclusion was reached: stem cells play a major role in stimulating hair follicles to produce new hair. Knowing this, Induchem’s laboratories have developed Redensyl with the role of reactivating hair follicles stem cells (HFSCs) and dermal papilla fibroblasts. If HFSCs activity increases, the telogen phase’s duration will decrease, followed by an increased ratio density of hairs in the anagen phase. It practically shortens the resting phase while more hair will be moved in the growing phase, leading to healthy hair growth.

Redensyl formulation explained

DHQG, used in the formulation of Redensyl, can stimulate the stem cells’ cellular activities in the ORS and dermal papilla, the two primary cells involved in new hair formation. In their study, Induchem’s laboratory claims that the metabolism in derma papilla stem cells improved from 12% to 24%, while the activity of ORS stem cells improved from 28% to 44%. Also, because an irritating scalp is more likely to affect hair quality, EGCG2 was added due to its anti-inflammatory properties. The other two compounds, glycine and zinc reinforce the hair shaft structure. 

How to use Redensyl?

Redensyl is found as an active ingredient in the formulation of hair serums and oils. Get yourself a Redensyl product and apply it as follows. First, rinse your hair thoroughly with warm water. Then place dropper on the scalp target areas and move through, squeezing gently to disperse small drops, not full droppers. Massage into scalp to ensure even distribution and then rinse off foam from hair with warm water. Do this for three months and notice if your hair loss condition is improved. 

Is it safe?

Because Redensyl is plant-based and bio-processed is believed to have little to no side effects at all. Most studies conducted on Redensyl haven’t reported any harmful side effects, suggesting Redensyl is a safe and risk-free ingredient for hair growth.

Frequently asked questions about Redensyl

  1. Does Redensyl thicken hair?

    Yes, besides reducing hair loss and encouraging new hair growth, Redensyl also thickens the existing hair, making it appear denser, voluminous, and healthier.

  2. Which is best, Redensyl or minoxidil?

    As they have different mechanisms to promote hair growth, it's difficult to compare them. Minoxidil is a vasodilator used to expand blood vessels and boost blood flow to the scalp in order to stimulate hair growth. Both minoxidil and Redensyl are research-backed treatments, and their effects on hair growth were demonstrated in clinical studies. However, compared to Redensyl, minoxidil is an FDA-approved treatment and has been subjected to more trials.

  3. How long does it take for Redensyl to work?

    Depending on your condition, it may take between 2 to 6 months to notice changes. Most studies performed on Redensyl reported visible improvements in hair count, density, and thickness after 3 months of daily use.

  4. Is Redensyl approved by the FDA?

    No, Redensyl is not FDA-approved. However, Redensyl does not lack scientific evidence, and its effects on hair have been proven in clinical trials multiple times.

  5. Can you mix Redensyl with other ingredients?

    Yes, you can use Redensyl in conjunction with other treatments or ingredients to boost the results, including minoxidil. In fact, minoxidil can act as a booster for Redensyl and, when used together, may encourage faster hair growth. Besides, Redensyl works great with Capixyl and Procapil, the other two breakthrough formulas for hair growth.

  6. Is Redensyl a DHT blocker?

    No, Redensyl does not have any mechanism to block DHT conversion. If elevated levels of DHT cause your hair loss condition, it's best to use a DHT blocker such as saw palmetto together with Redensyl.
