Saw palmetto is often discussed as a potential supplement for addressing hair loss and promoting hair growth. However, it’s important to note that the effectiveness of saw palmetto for hair loss is still a subject of debate, and more research is needed to establish its efficacy and optimal dosage.
The recommended dosage of saw palmetto for treating hair loss can vary depending on factors such as the individual’s specific condition, overall health, and the formulation of the saw palmetto product being used. It is important to consult with a healthcare professional or a dermatologist for personalized advice. That being said, here are some commonly suggested dosages for saw palmetto for hair loss:
Oral Capsule Dosage:
The recommended dosage of saw palmetto capsules for hair loss often ranges from 160 mg to 320 mg of standardized extract per day. This can be taken as a single dose or divided into two equal doses. However, individual responses may vary, and it is best to follow the guidance of a healthcare professional.
Several studies have investigated the potential benefits of saw palmetto in treating hair loss, but the results have been mixed. Some studies suggest that saw palmetto may inhibit the enzyme 5-alpha-reductase, which converts testosterone into dihydrotestosterone (DHT), a hormone believed to contribute to hair loss. By reducing DHT levels, saw palmetto may help slow down hair loss and promote hair growth.
Here are a few studies that provide information regarding the dosage of saw palmetto used:
- Rossi et al. (2012): This study compared the effectiveness of finasteride with Serenoa repens (saw palmetto) in male androgenetic alopecia. The daily dosage of saw palmetto used in the study was 320 mg in the form of an oral capsule.
- Prager et al. (2002): This randomized, double-blind, placebo-controlled trial investigated the effectiveness of botanically derived 5-alpha-reductase inhibitors, including saw palmetto, in the treatment of androgenetic alopecia. The daily dosage of saw palmetto used in the study was 200 mg in the form of an oral supplement.
- Wessagowit et al. (2016): In this study, the efficacy of topical products containing saw palmetto extract for male androgenetic alopecia was evaluated. The dosage used was 50 mg of saw palmetto extract applied topically twice daily.
It’s important to note that these are just a few specific studies, and the dosages used may vary in other studies or formulations. Additionally, the quality of the saw palmetto extract is of concern as some is better than others. A higher quality extract may require a smaller dosage and vice versa. Also, these studies focused on male hair loss. Female hair loss may occur for different reasons.
Saw Palmetto For Hair Loss In Females – Dosage
It is not recommended for pregnant women to use saw palmetto as its potential affect on hormones may adversely affect the development of the embryo – especially male embryos. In Review of Antiandrogenic Risks of Saw Palmetto Ingestion by Women, the author states:
At the present time, the weight of scientific evidence suggests that consumption of saw palmetto poses a risk to unborn male fetuses. This overall public health concern is mitigated somewhat by the much lower popularity of saw palmetto with women, but as noted previously, saw palmetto use is not limited to men. In summary, unless information becomes available to suggest that the antiandrogenic activity in humans is not high enough to cause birth defects in male offspring, a concern exists.
The scientific evidence regarding saw palmetto’s effectiveness and safety specifically for female hair loss is limited and somewhat inconclusive. Most studies on saw palmetto for hair loss have focused on men with androgenetic alopecia (male pattern baldness). However, there are some anecdotal reports and studies that touch upon its use in women.
Polycystic ovary syndrome (PCOS): Some women with PCOS experience hair loss as a result of hormonal imbalances. Saw palmetto has been suggested as a natural remedy to address hair loss associated with PCOS. However, the evidence supporting its efficacy in this context is limited, and more research is needed.
A study published in the Journal of Cosmetic Dermatology in 2018 investigated the effects of a topical lotion containing saw palmetto extract on female pattern hair loss. The study involved 50 women with hair thinning or hair loss, and the lotion was applied twice daily for three months. The researchers reported a significant improvement in hair density and thickness based on clinical evaluations and trichogram analysis. However, this was a small-scale study, and further research is needed to confirm the findings.
Another study published in the Journal of Alternative and Complementary Medicine in 2002 evaluated the efficacy of saw palmetto in 10 women with androgenetic alopecia (female pattern hair loss). Participants received an oral supplement containing 200 mg of saw palmetto extract for two years. The study found a subjective improvement in hair growth in six out of 10 participants. However, this was a small, open-label study without a control group, and larger, controlled studies are necessary to validate the results.
Some women may find saw palmetto helpful for hair loss, while others may not experience noticeable benefits. Factors such as underlying causes of hair loss, hormonal profile, and individual variations can influence the outcomes.
Consultation with healthcare professionals: Due to the limited scientific evidence and potential hormonal effects, it is crucial for women considering the use of saw palmetto for hair loss to consult with a healthcare professional or a dermatologist. They can assess the individual’s specific condition, provide appropriate guidance, and consider any potential interactions or contraindications.
