While it's normal to shed a few strands of hair daily, most of us still desire a thick, healthy mane. However, hair loss has become a widespread issue affecting people of all ages, genders, and backgrounds. If you're tired of using anti-hair fall shampoos or are exploring other natural remedies like rosemary oil or onion for hair growth, it’s time to consider saw palmetto. This shrubby palm is commonly used as a herbal extract and can be found in supplements and hair care products. Let’s explore whether saw palmetto can really help promote hair growth.

Saw palmetto benefits

Saw palmetto could be the solution you've been searching for in haircare. Its berries are packed with fatty acids and phytosterols, making it a sought-after natural remedy in both health and cosmetic treatments. "With its anti-inflammatory and hormone-regulating properties, saw palmetto is known to support prostate health and reduce hair fall," explains Dr. Karuna Malhotra, an aesthetic physician and cosmetologist.

According to the US National Center for Complementary and Integrative Health, saw palmetto is used as a supplement for:

• Urinary symptoms connected with an enlarged prostate gland
• Chronic pelvic pain
• Migraine
• Hair loss

Saw palmetto benefits: Know if it can promote hair growth

Saw palmetto is available in various forms for hair care, including supplements, shampoos, and hair oils. It is believed to help manage hair loss and promote hair growth. A 2023 study in Clinical, Cosmetic and Investigational Dermatology found that saw palmetto oil can reduce hair fall and encourage hair growth in individuals experiencing hair loss. Additionally, a 2020 study published in the Skin Appendage Disorders Journal showed positive results from both topical and oral supplements containing saw palmetto. The study revealed that 60% of participants experienced improved hair quality, while 83.3% saw an increase in hair density after using these supplements.

"Saw palmetto benefits include supporting hair health due to its ability to inhibit 5-alpha-reductase, an enzyme that converts testosterone into dihydrotestosterone (DHT)," says Dr Malhotra. Elevated levels of DHT may lead to hair follicle shrinkage, and cause hair loss.

Here's what makes hair growth part of saw palmetto benefits:

• Prevents follicle shrinkage: Saw palmetto blocks dihydrotestosterone or DHT, a hormone that causes hair follicle miniaturisation, a condition that makes it harder for hair to grow, and hair loss.
• Supports new hair growth: It extends the anagen or growth phase of the hair cycle. This helps in encouraging hair regrowth.
• Reduces inflammation: It can reduce inflammation and promote a healthy scalp, aiding follicle function. Saw palmetto has anti-inflammatory properties, according to a 2015 study published in Phytotherapy Research.
• Balances scalp oil production: Saw palmetto benefits hair as it regulates sebum production, preventing the scalp from becoming excessively oily. This helps reduce clogged hair follicles, which can lead to hair thinning.
• Improves scalp health: Its anti-inflammatory and antimicrobial properties alleviate conditions like dandruff and itchiness. "A healthier scalp environment is a must for stronger and more resilient hair growth," says the expert.
• Reduces hair thinning: "It combats hormonal imbalances, especially during menopause or postpartum periods," says the expert. This makes it effective for maintaining hair density and preventing further hair loss.

Hair growth may be one of the saw palmetto benefits and is generally safe, but it can cause side effects such as:

• While saw palmetto offers several benefits, there are some potential side effects to be aware of. Mild digestive issues, such as nausea, diarrhea, or constipation, may occur, especially when the supplement is taken on an empty stomach. To minimize these effects, it's advised to consume saw palmetto with food, according to experts.
• Topical use may also cause allergic reactions, such as redness, itching, or rashes, particularly for individuals with sensitive skin. A patch test is recommended before applying it to the scalp.
• Pregnant or breastfeeding women should avoid saw palmetto, as it may interfere with hormone levels and potentially impact fetal development, Dr. Malhotra warns.
• Additionally, saw palmetto can have blood-thinning effects, increasing the risk of bleeding, particularly when used alongside anticoagulants or aspirin. It is advised to stop using the supplement at least two weeks before undergoing surgery.
