During the colder months, experiencing hair loss, thinning, or fallout can be distressing. Seeking the guidance of a dermatologist is vital to find the most effective treatment for your specific needs. With that said, we reached out to doctors and hair experts who shared three shampoo ingredients that may cause or worsen hair loss or thinning, and two essential ingredients that promote fuller and thicker growth while rejuvenating dry, brittle, and lackluster hair.

3 Shampoo Ingredients That Often Exacerbate Hair Loss And Thinning

1. Silicones

Silicones, commonly found in shampoos, are often portrayed as beneficial due to their ability to enhance shine and gloss. However, Factor stresses, their detrimental impact on scalp health should not be ignored as they can stifle its ability to receive necessary nourishment. "Silicones in shampoo can cause hair loss by coating the scalp so that nutrients cannot be absorbed," she warns.

2. Parabens

The presence of parabens in shampoos may lead to a host of hair-related issues, Factor tells us. These include "dryness and scalp irritation" as well as "fading hair color and hair loss." Since they are "generally unsafe," she says "it is best to avoid parabens until proven otherwise."

3. Sodium Chloride

According to Harth, sodium chloride, a frequent component of mass-produced shampoos, is not recommended for women who are experiencing hair loss or thinning.

Commonly used to thicken shampoos and conditioners, it can "dry the scalp, causing redness and itching," Harth notes, and this scalp irritation can "damage hair follicles and cause more hair loss."

2 Healthier Shampoo Ingredients That Promote Hair Growth

1. Biotin

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, Abdullah 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.”

2. Saw Palmetto

Incorporating saw palmetto into your shampoo can prove to be advantageous in reducing hair loss, Hilton 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

Overall, Kung stresses 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. She 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 shampoos that contain biotin and saw palmetto, as suggested by our experts.
