6 Best Shampoos That Can ‘Prevent Hair Loss,’ According To Experts—#6 ‘Stimulates Hair Follicles’

Randon's video provided valuable information but was brief, so we consulted dermatologists and hair specialists to find out which shampoo ingredients to avoid if you have fine, thinning hair and are over 40.

Dr. Elaine Kung, MD, FAAD, founder of Future Bright Dermatology, tells SheFinds that choosing the right shampoo for your hair is crucial as "shampoos are not only scalp cleaners, but indubitably act as preventing the hair shaft damage." Many scalp diseases are also "treated by active ingredients that are added to the shampoo's formulations," she says.  

2 Shampoo Ingredients That Can Revive Dry, Brittle And Thinning Hair

1. Biotin (Vitamin B7)

Biotin (aka vitamin B₇) is an important nutrient often found in foods like eggs, broccoli, bananas and milk. Many people take biotin as a supplement as they age, Ghanima Abdullah, hair expert and cosmetologist at The Right Hairstyles explains, to strengthen their tresses. If also using a shampoo with biotin as a main ingredient, one can really reap the benefits of this vitamin in more ways than one. “Biotin is the ingredient to look for in shampoo if you want thicker, fuller, healthier hair,” Abdullah says.

Abdullah highlights the benefits of incorporating biotin-infused shampoo into one's hair care routine, which includes enhancing hair growth, relieving discomfort associated with itchy hair, and mitigating other hair conditions commonly experienced during the winter season. “Not only can it be taken as a supplement, but when used in shampoo the ingredient goes directly into the hair follicles.”

She notes that biotin helps increase circulation to the scalp, which helps the hair follicles produce a better quality of hair and more of it. “It's believed that a deficiency of biotin leads to hair loss,” she adds, so using shampoo with biotin is one of the “easiest ways to help reverse the effects of aging on hair, which can manifest as thinning and brittleness.”  

2. Saw Palmetto

Incorporating saw palmetto into your shampoo can prove to be advantageous in reducing hair loss, Dr. Rebecca Hilton, hair expert at J-Beauty says, as it is a highly sought-after ingredient in the realm of hair care. "Saw palmetto is a natural extract from the berries of the Serenoa repens plant and has been used for centuries for the treatment of various conditions including hair loss," she explains.

Hilton adds that "saw palmetto works by blocking the production of DHT," which helps to "reduce hair shedding." Kung concurs, and points out that because saw palmetto is a DHT blocker, it is "helpful in the treatment of female pattern baldness that can become quite apparent when a woman is in her 40s."  

The Bottom Line

Kung concludes that "shampoos are typically composed of 10–30 ingredients, although products with as few as four ingredients are available."

While awaiting a doctor's recommendation for a tailored treatment for your hair and scalp, it is recommended to keep a lookout for products that contain biotin and saw palmetto, as suggested by our experts.
