Plus, more strand-thickening favorites.

French brand René Furterer has been in the hair-growth scene for decades, long preceding the recent categorical influx. Case in point: I discovered the brand nine years ago, at the beginning of my career, via editors and experts who raved about its Triphasic serums—among other fullness-promoting formulas. 

This Labor Day weekend, you can snag best-selling thickening solutions, including the famous Triphasic serums, at a discount. Specifically: Score 20 percent off of your order when you buy two full-sized products—or, purchase at least three products and receive 30 percent off of your order. 

At checkout, input the code FULL20 for 20 percent off of two items, or FULL30 for 30 percent off of three or more products. If strong, thick, healthy hair is your goal, I’d advise stocking up on as many of these growth-promoting goodies as you can. Hurry—deals end September 2.

Triphasic Recreational Concentrated Serum

This set is created to treat sudden, situational hair loss—and shoppers attest to its effectiveness. For instance, one reviewer, who had been shedding, reported they can run their hands through their mane and “not one hair comes out” thanks to the serum. Complete with a three-month supply of single-use ampoules, this rinse-free treatment is lightweight, non-greasy, and straightforward to use. The drug-free formula is powered by plant extracts, including strengthening wheat protein and ATP—an ingredient that energizes cells in the hair follicle, and ultimately spurs growth.

Yet another popular growth-stimulating serum set, this three-month supply tackles hereditary hair loss via plant extracts that address genetic shedding. Watercress extract, which thickens hair and spurs growth, is a key ingredient. Additionally, orange oil improves cellular turnover on the scalp, thus allowing hair follicles to flourish. One study even determined limonin, found in citrus fruits including orange extract, stimulates new hair growth.

Healthy hair begins with a healthy scalp—which is precisely the purpose of this lightweight serum. After one month, the leave-in treatment noticeably strengthens strands, per the brand. Shoppers attest to these fortifying claims. Moreover, one reviewer—who has been using the serum for 20 years—loves that it gives their oily, limp hair noticeable “volume.” Another reviewer said they saw more than three inches of growth after using it for just six months. 

Triphasic Thickening Shampoo

This strand-plumping shampoo boosts volume after a single use. The formula features vitamin B5, a.k.a pantothenic acid, which smooths and hydrates strands; furthermore, the ingredient may help lengthen and thicken over time. Similarly, rosemary oil improves blood flow to the follicles, which ultimately quickens growth. As for instant effects, one shopper over 55 with “really fine, thin hair” says the formula is among the few that “truly works.”

For longer, stronger, thicker hair and a healthier scalp, shop the French hair brand backed by shopper acclaim and science, René Furterer, while it’s discounted until September 2. Shop more strand-plumping products, below.
