Cortisone shots rarely cause hair loss directly, but side effects and underlying conditions may contribute to temporary shedding.
Understanding Cortisone Shots and Their Purpose
Cortisone shots, also known as corticosteroid injections, are widely used to reduce inflammation and relieve pain in various medical conditions. These injections deliver a synthetic form of cortisol, a hormone naturally produced by the adrenal glands, directly into affected areas like joints, tendons, or soft tissues. The primary goal is to calm down inflammation quickly and provide relief from symptoms caused by arthritis, bursitis, tendonitis, or allergic reactions.
Doctors often recommend cortisone shots when oral medications or physical therapy fail to ease symptoms. They can be incredibly effective in reducing swelling and improving mobility. However, like any medical treatment, cortisone injections come with potential side effects that patients should consider before proceeding.
The Connection Between Cortisone Shots and Hair Loss
The question “Can Cortisone Shots Cause Hair Loss?” pops up frequently among patients concerned about side effects. The short answer: direct hair loss from cortisone shots is uncommon but not impossible. It’s important to unpack the mechanisms behind this concern.
Hair follicles are sensitive to hormonal changes and immune system activity. Since cortisone affects immune responses and hormone levels locally or systemically (if injected frequently or in high doses), it can indirectly influence hair growth cycles.
In most cases, localized cortisone injections do not significantly alter hair growth because the medication stays confined to the injection site. However, repeated or high-dose systemic corticosteroid use may disrupt the natural hair cycle phases—anagen (growth), catagen (transitional), and telogen (resting)—leading to increased shedding or thinning.
How Steroids Impact Hair Follicles
Corticosteroids have complex effects on the body’s immune system. They suppress inflammation but also influence cell metabolism and protein synthesis. Hair follicles are mini-organs that undergo constant regeneration, relying on a delicate balance of hormones and immune signals.
When steroids alter this balance:
- Telogen Effluvium: A common form of temporary hair loss triggered by stressors such as medication changes or illness.
- Alopecia Areata: An autoimmune condition where immune cells attack hair follicles; steroids are sometimes used as treatment here.
In some cases, high systemic doses of corticosteroids may push more hair follicles into the resting phase prematurely, causing noticeable shedding weeks after treatment.
Systemic vs Local Cortisone Effects on Hair Loss
The risk of hair loss varies significantly between local cortisone shots and systemic steroid therapy:
- Local Injections: These deliver medication into a specific joint or tissue area with minimal absorption into the bloodstream. Hair loss from local shots is very rare unless injected near scalp skin repeatedly.
- Systemic Steroids: Oral or intravenous corticosteroids affect the entire body, increasing chances of side effects including hormonal imbalances that can trigger hair shedding.
Understanding this distinction helps clarify why most patients receiving localized cortisone shots do not experience hair loss.
Cumulative Dose Matters
Repeated cortisone injections over short periods can raise systemic steroid levels enough to cause side effects usually linked with oral steroids. This cumulative exposure increases risks for complications such as skin thinning around injection sites and potential impacts on hair follicles.
Doctors typically limit the number of cortisone shots per joint annually to minimize these risks.
Other Factors Influencing Hair Loss After Cortisone Shots
Hair loss after cortisone shots might not stem directly from the medication itself but from related factors:
- Underlying Medical Conditions: Diseases treated by cortisone—like autoimmune disorders—may independently cause hair thinning.
- Stress: Chronic pain or illness leading to stress can trigger telogen effluvium.
- Nutritional Deficiencies: Poor nutrition during illness recovery may worsen hair health.
- Injection Site Reactions: Rarely, localized skin atrophy or damage around injection areas could affect nearby scalp follicles if close enough.
These elements often muddy the waters when attributing hair loss solely to cortisone shots.
The Science Behind Corticosteroids and Hair Growth Cycles
Hair follicles cycle through phases that determine growth and shedding rates:
| Phase | Description | Duration |
|---|---|---|
| Anagen (Growth) | The active phase where hair cells rapidly divide forming new strands. | 2-7 years |
| Catagen (Transition) | A brief period signaling end of growth; follicle shrinks preparing for rest. | 2-3 weeks |
| Telogen (Resting) | The follicle rests before old hairs shed naturally; new cycle begins afterward. | 3 months approx. |
Corticosteroids can push follicles prematurely into telogen phase by altering immune signals or hormone levels. This shift causes more hairs than usual to shed simultaneously—a pattern typical of telogen effluvium.
Steroid-Induced Telogen Effluvium Explained
Telogen effluvium is a reversible condition where a shock to the system forces many follicles into resting phase at once. Common triggers include surgery, illness, medications like steroids, hormonal shifts, or severe stress.
Steroid use can mimic these triggers through:
- Suppressing inflammatory cytokines that regulate follicle cycling.
- Affecting adrenal hormones that indirectly impact scalp health.
- Cumulative toxicity with repeated doses causing systemic imbalance.
Fortunately, once steroid exposure ceases or stabilizes, normal anagen cycles resume and hair regrows over several months.
Treatment Options for Hair Loss Related to Cortisone Use
If you suspect your hair thinning relates to cortisone shots—or any steroid treatment—there are steps you can take:
- Consult Your Doctor: Before stopping any prescribed steroid therapy; abrupt withdrawal can cause other health issues.
- Diet & Nutrition: Support your body with protein-rich foods, vitamins like biotin and zinc known for promoting healthy hair growth.
- Mild Topical Treatments: Over-the-counter minoxidil may help stimulate regrowth in some cases after medical clearance.
- Avoid Excessive Styling Stress: Limit heat styling tools and harsh chemicals while your scalp recovers.
- Mild Scalp Massage: Encourages blood flow which nourishes follicles during regrowth phases.
Patience is key since steroid-induced shedding typically reverses once triggering factors subside.
The Role of Medical Supervision in Managing Side Effects
Never self-medicate or change dosages without professional guidance. Your healthcare provider might adjust treatment plans if side effects become troublesome. Sometimes switching injection sites or spacing out treatments reduces risk without compromising benefits.
For persistent hair loss unrelated to steroid doses, dermatologists might explore other causes such as androgenetic alopecia or autoimmune conditions needing targeted therapies beyond corticosteroids.

Frequently Asked Questions
Can Cortisone Shots Cause Hair Loss Directly?
Cortisone shots rarely cause hair loss directly. Most injections stay localized and do not affect hair follicles significantly. However, repeated or high-dose corticosteroid use may disrupt hair growth cycles, potentially leading to temporary shedding.
How Do Cortisone Shots Affect Hair Growth Cycles?
Corticosteroids can influence the phases of hair growth by altering hormone levels and immune responses. This disruption may push hair follicles into the resting phase, causing temporary thinning or shedding known as telogen effluvium.
Is Hair Loss from Cortisone Shots Permanent?
Hair loss linked to cortisone shots is usually temporary. Once the medication’s effects wear off and hormone balance restores, normal hair growth typically resumes without lasting damage to follicles.
Can Underlying Conditions Treated by Cortisone Shots Cause Hair Loss?
Yes, sometimes the medical conditions requiring cortisone shots—like autoimmune diseases—can themselves cause hair loss. It’s important to distinguish whether shedding is due to the condition or the treatment.
Are There Ways to Prevent Hair Loss When Receiving Cortisone Shots?
To minimize risk, follow your doctor’s dosage recommendations and avoid frequent high-dose injections. Maintaining overall health and managing stress can also help support healthy hair growth during treatment.
The Bottom Line: Can Cortisone Shots Cause Hair Loss?
To wrap it up clearly: Can Cortisone Shots Cause Hair Loss? Yes—but only under certain circumstances involving dose size, frequency of administration, individual sensitivity, and underlying health conditions. Localized injections seldom lead directly to noticeable shedding unless administered repeatedly near scalp areas.
Hair loss linked with corticosteroids usually manifests as temporary telogen effluvium rather than permanent baldness. Most patients recover fully once treatments conclude or stabilize without long-term consequences.
Understanding these nuances helps set realistic expectations around cortisone shot side effects while appreciating their powerful role in managing painful inflammatory conditions safely when used judiciously.
Keeping open communication with your healthcare provider about any concerns ensures balanced care tailored specifically for you—minimizing risks while maximizing relief benefits from cortisone therapies.
