The Benefits of Horsetail

Horsetail for hair growth has been studied over the years, and the research results support its efficacy in treating various ailments. It is an ancient herb used for thousands of years to treat and improve bone health, regulate blood flow, and maintain skin and hair health. It also exhibits anti-inflammatory, anti-fungal, and anti-microbial properties that can help fight infection. The most recent research has indicated that horsetail’s anti-inflammatory effects and antioxidants have proven valuable for hair health.

What is Horsetail?

The main ingredient in horsetail is the mineral silica. It is the alkalizing property that is responsible for strengthening hair strands and improving hair sheen and texture. 

Another essential health component of horsetail is selenium. Selenium helps the body process iodine, which is responsible for boosting hair growth and maintaining its strength. And because of its anti-bacterial properties, it helps fight infection on your scalp, clearing follicles and roots to support healthy hair growth.

Horsetail Research Demonstrates Positive Outcomes in Hair Growth

Researchers investigated the natural food supplement’s efficacy and tolerability in a recent controlled study titled “Objective and Subjective Effects and Tolerability in Persons with Hair Loss” (1). The supplement included marine proteins, minerals, vitamins, and horsetail herbs. These ingredients are suspected to be effective in treating hair loss. 

Fifty-five subjects with hair loss participated in the 6-month blind study. All subjects had hair-loss problems of at least 1 year before entering the study. Subjects were exposed to either the food supplement or a placebo for approximately 6 months. After 6 months, the placebo group was given the supplement that contained marine proteins, minerals, vitamins, and horsetail extract, among other ingredients. This product is intended to supply the hair follicles with nutrients necessary for the hair’s growth and quality.

The Findings

Hair counting was done to identify the results. The group using the supplement achieved positive results with an average hair growth increase of 35.7%. On the other hand, the subjects in the placebo group showed only a 1.5% improvement. Therefore, this study shows that the subjects reported more favorable hair gain with the supplement containing horsetail than the placebo.

More so, this study also indicates that this supplement may be a viable option for treating hair loss. It is also possible that the ingredients, including horsetail, might be related to the decrease in the production of dihydrotestosterone (DHT) in the body.

The hormone testosterone is responsible for converting to DHT with the aid of the enzyme 5-alpha reductase. DHT inhibits hair growth by shrinking the follicles when this occurs, which eventually prevents healthy hair growth. 

Using horsetail for hair growth contributes to healthy hair by strengthening and regulating growth.
In short, using horsetail for hair growth contributes to healthy hair by strengthening and regulating growth.

Study Shows Promise for Horsetail Enhancing Hair Growth in Oral Supplement

In a second study titled, A Double-Blind, Placebo-Controlled Study Evaluating the Efficacy of an Oral Supplement in Women with Self-Perceived Thinning Hair (2), a controlled study was conducted to evaluate the efficacy of an oral supplement in women with perceived hair loss.

Specifically, this random, placebo-controlled, double-blind study was designed to test whether administering a new oral supplement will increase hair growth in adult women. Most participants complained of self-perceived thinning hair associated with poor diet, stress, and hormonal influences. The women participated in the study for 6-Months.

The study included women between 21 to 75 years of age with Fitzpatrick skin types I to IV. The Fitzpatrick scale is used to classify a person’s complexion concerning their tolerance to sunlight. The women were generally in good health but complained of self-perceived hair loss. The subjects were randomized in a double-blind fashion to receive the new oral supplement or the placebo. The oral supplement contained the AminoMar C marine complex, a proprietary blend of shark and mollusk powder, vitamin C, an organic form of silica derived from horsetail, and several other ingredients. The study evaluated subjects treated with the medication for three months.

The Results

The mean number of terminal hairs in the target scalp area increased from 271 at baseline to 571. After six months, the mean number increased further to 609.6. This growth in the number of hairs was significantly higher than the mean number of terminal hairs among the placebo-treated subjects at baseline (256.0).

These results support the hypothesis that the oral supplement containing horsetail extract increases hair growth in women with thinning hair. In addition to the hair growth, improvements occurred in overall hair volume, thickness, hair shine, and moisture retention. Therefore, this study suggests that horsetail for hair growth is a valid claim. In conclusion, the daily dose of a proprietary supplement containing horsetail significantly increases hair growth after 90 and 180 days with no adverse effects to report.

Based on this and other numerous studies’ work and research, horsetail can enhance the hair’s texture, strength, and shine to promote hair growth.

Does Horsetail Have Side Effects

When taken orally, horsetail is “possibly unsafe.”

Its thiaminase content breaks down thiamine which may lead to a thiamine (vitamin B1) deficiency. Horsetail also contains nicotine and should be avoided if you are allergic to this constituent. Horsetail should be avoided if you are pregnant, lactating, or suffer from conditions such as:

  1. Hypokalemia (i.e., low potassium)
  2. Thiamine deficiency
  3. Alcohol disorders
  4. Diabetes

Be sure to consult your physician before deciding to take horsetail or any other supplement.

Safety Profile

According to the FDA, the safety of horsetail extract is currently “undefined.” However, the EWG (Environmental Working Group) did assign horsetail a toxicity/hazard rating of 1 out of a 10 point scale with little to no risk of cancer, developmental or reproductive toxicity, allergies, or immunotoxicity.

General Horsetail Uses

The horsetail herb has long been prized for its anti-bacterial, anti-microbial, antioxidant, astringent, coagulant, diuretic, and demulcent activity. Today, people continue to take horsetail extract for

  1. “Fluid retention” (edema) purposes,
  2. Urinary incontinence (loss of bladder control)
  3. Wound healing
  4. Urinary tract infections
  5. Increasing urine output (due to its diuretic effects)

Additional applications include:

  1. Osteoarthritis
  2. Weight loss
  3. Heavy menstrual periods
  4. Bladder/ kidney stones
  5. Frostbite
  6. Gout

While horsetail is available as capsules, horsetail can also be used in the form of teas, mixtures, and liquid tinctures.

Simultaneously, safe and effective dosage standards have yet to be established due to a lack of research.

While horsetail can offer many health benefits, its effectiveness would ultimately depend on how it is processed. Heat, for example, can destroy essential plant constituents that we rely on for healing and well-being, particularly for its hair growth or hair restoration benefits.
