Do SARMs Cause Hair Loss? Uncover the Truth with These 5 Facts

Hair loss is a significant concern for many considering the use of SARMs (Selective Androgen Receptor Modulators). While SARMs are popular for their muscle-building benefits, potential side effects and questions arise like: do SARMs cause hair loss; this can be a deal-breaker.

This article delves into whether SARMs cause hair loss, supported by scientific studies and user experiences.

SARMs are designed to selectively target androgen receptors in muscles and bones, promoting growth without the widespread side effects of anabolic steroids.

However, their interaction with androgen receptors can still impact hair follicles.

Key Points to Consider

  1. Androgen Sensitivity: SARMs like RAD-140 and LGD-4033 can cause hair loss in individuals with a genetic predisposition to androgen sensitivity.
  2. DHT Conversion: Unlike traditional steroids, SARMs do not convert to dihydrotestosterone (DHT), a primary cause of androgenic alopecia.
  3. Dosage and Duration: Higher doses and prolonged use of SARMs increase the likelihood of side effects, including potential hair loss.
  4. Individual Variation: Responses to SARMs vary widely; some users report significant hair loss, while others experience none.
  5. Stacking with Non-SARMs: Combining SARMs with other compounds like MK-677 (a growth hormone secretagogue) might influence hair health.

RAD-140SARMModerateCan cause hair loss in androgen-sensitive individuals
LGD-4033SARMModeratePotentially increases androgenic activity
Ostarine (MK-2866)SARMLowLeast likely among SARMs to cause hair loss
S4 (Andarine)SARMHighKnown for vision side effects, also linked to hair loss
YK-11SARMModerateMyostatin inhibitor, potential for hair follicle impact
MK-677Non-SARMLowPromotes hair growth through GH and IGF-1 stimulation
GW-501516Non-SARMNoneNo known effect on hair follicles
SR9009Non-SARMNoneNo androgenic activity, thus no hair loss risk

Relevant Studies

  • Study on Androgen Receptors and Hair Follicles: Research shows that hair follicles contain androgen receptors, and their activation by androgens like testosterone and its derivatives can lead to hair thinning and loss (r).
  • Effects of SARMs on Androgen Receptors: A study published in the Journal of Medicinal Chemistry demonstrated that certain SARMs can activate androgen receptors in hair follicles, potentially leading to hair loss in predisposed individuals (r).
  • Minoxidil and Hair Regrowth: Clinical trials have shown that Minoxidil can effectively stimulate hair growth in individuals experiencing hair loss (r).
  • Finasteride and Androgenic Alopecia: Studies have demonstrated that Finasteride significantly reduces DHT levels, leading to decreased hair loss and increased hair regrowth in men with androgenic alopecia (r).

Mitigating Hair Loss While Using SARMs

To minimize the risk of hair loss while using SARMs, consider the following strategies:

  • Use Lower Doses: Stick to the recommended dosages and avoid high doses.
  • Limit Cycle Duration: Shorter cycles reduce the likelihood of side effects.
  • Monitor Hair Health: Regularly check for signs of hair thinning and adjust usage accordingly.
  • Consider PCT (Post Cycle Therapy): Use a proper PCT to restore hormonal balance post-cycle, which may help in mitigating hair loss.

Reversing Hair Loss: Effective Treatments

If you’re experiencing hair loss due to SARMs or other factors, several treatments can help reverse or minimize the damage. These treatments range from topical applications to oral medications and lifestyle changes.

Topical Treatments

  1. Minoxidil (Rogaine): This over-the-counter treatment is applied directly to the scalp and helps stimulate hair growth by increasing blood flow to hair follicles.
  2. RU-58841: An experimental androgen receptor antagonist that can be applied topically to prevent DHT from binding to hair follicles, thus reducing hair loss.

Oral Medications

  1. Finasteride (Propecia): A prescription medication that reduces DHT levels in the body, helping to prevent hair loss and promote regrowth.
  2. Dutasteride (Avodart): Similar to Finasteride but more potent, it’s used to treat more severe cases of androgenic alopecia.

Lifestyle Changes

  1. Healthy Diet: Eating a balanced diet rich in vitamins and minerals can improve overall hair health. Focus on foods high in vitamins A, C, D, E, zinc, iron, and omega-3 fatty acids.
  2. Stress Management: Chronic stress can exacerbate hair loss. Practices such as yoga, meditation, and regular exercise can help reduce stress levels.


While SARMs can potentially cause hair loss, especially in genetically predisposed individuals, the risk varies based on the type of SARM, dosage, and individual sensitivity. By understanding these factors and following best practices, you can make an informed decision about using SARMs.

Can everyone experience hair loss with SARMs?


Only individuals with a genetic predisposition to androgen sensitivity are more likely to experience hair loss.

Is hair loss from SARMs permanent?


Hair loss caused by SARMs is typically reversible once the use is discontinued, especially with proper PCT.

By staying informed and cautious, you can enjoy the benefits of SARMs while minimizing unwanted side effects.
