A buyer was able to grow her hair by 7.5 cm with this serum from Rene Furterer

French brand René Furterer has been active in the hair growth scene for decades and has long since left the latest trend behind. Case in point: I discovered the brand nine years ago, at the start of my career, through editors and experts who raved about their Triphasic serums – among other fuller-volume formulas.

René Furterer hair growth offers:

Three-phase, concentrated leisure serum

This kit is designed to treat sudden, situational hair loss—and shoppers attest to its effectiveness. For example, one reviewer who was experiencing hair loss reported that thanks to the serum, he could run his hands through his mane and “not a single hair fell out.” This rinse-free treatment, which comes with a three-month supply of disposable vials, is lightweight, non-greasy, and easy to use. The drug-free formula contains plant extracts, including strengthening wheat protein and ATP—an ingredient that energizes cells in the hair follicle and ultimately stimulates growth.

Three-phase progressive concentrated serum

Another popular growth-stimulating serum kit, this three-month supply fights hereditary hair loss using plant extracts that fight genetic hair loss. Watercress extract, which thickens hair and stimulates growth, is a key ingredient. Additionally, orange oil improves cell renewal on the scalp, allowing hair follicles to thrive. One study even found that limonin, found in citrus fruits like orange extract, stimulates new hair growth.

Head Spa Complexe 5 Stimulating Plant Concentrate

Healthy hair starts with a healthy scalp—and that’s exactly the purpose of this lightweight serum. According to the brand, the leave-in treatment noticeably strengthens strands after just one month of use. Shoppers back up these strengthening claims. What’s more, one reviewer who has used the serum for 20 years is thrilled that it adds noticeable “volume” to his oily, limp hair. Another reviewer said he saw more than three inches of growth after just six months of use.

Three-phase thickening shampoo

This hair-plumping shampoo adds volume after just one use. The formula contains vitamin B5, also known as pantothenic acid, which smooths and moisturizes strands; it can also help hair grow longer and thicker over time. Likewise, rosemary oil improves blood flow to the follicles, which ultimately accelerates growth. As for immediate results, one 55+ shopper with “really fine, thin hair” says the formula is one of the few that “really works.”

For longer, stronger, thicker hair and a healthier scalp, shop French hair brand René Furterer, backed by shoppers and science, while it’s discounted through September 2. Shop more products for more volume below.
