Steroid injections for alopecia areata are one of the most common first-line treatments for patchy (limited) alopecia areata, especially in adults. These injections are placed directly into the skin of the bald patch to reduce the local immune attack on hair follicles and help regrowth.
Medical note: This article is for general education and does not provide personal medical advice. Steroid injections should be performed by a qualified clinician (usually a dermatologist). If you have rapid spread, scalp pain/burning, heavy scale/crusting, or a child with patchy loss and scale (possible fungal infection), see a clinician promptly.

Key takeaways (fast)
- Best fit: small, patchy alopecia areata (limited scalp involvement), especially in adults.
- Common schedule: injections are often repeated every 4–6 weeks if the clinician thinks you’re responding.
- Timeline: early regrowth may appear in weeks to a few months; many clinicians reassess around ~3 months.
- Important limitation: injections can help regrow hair in treated patches, but they do not guarantee prevention of new patches elsewhere.
- Main local side effect: temporary skin dents/dimples (atrophy/lipoatrophy) can happen at injection sites.
What the injections are (plain English)
These are intralesional corticosteroid injections (often triamcinolone) placed directly into the skin of the bald patch. The idea is to calm local inflammation around the hair follicles so the follicles can restart growing hair.
This is different from:
- Topical steroids (creams/solutions you apply at home), and
- Systemic steroids (pills), which affect the whole body and have a different risk profile.
On this site, this topic fits under: Treatment Overview and Non-Scarring Alopecia.
Who they help most (and who may need another plan)
Most likely to benefit
- Adults with a few patches of alopecia areata (patchy/limited disease).
- Localized scalp, beard, or eyebrow patches (clinician-selected cases).
- People who can attend repeat appointments every few weeks.
When injections may NOT be the main plan
- Extensive/widespread alopecia areata (many patches, totalis, universalis): patch injections may not be practical as the main strategy.
- Rapidly progressive disease: a dermatologist may discuss other options sooner.
- Young children: topical corticosteroids are often used first, and treatment choices differ by age and extent.
For parents: If the patient is a child, read: Alopecia Areata in Children: Parent Guide (diagnosis, watchful waiting, first-line treatment, and urgent red flags).

What happens during a treatment session
- Diagnosis check first: your dermatologist confirms the patch is consistent with alopecia areata (and not another cause such as fungal infection or scarring alopecia).
- Targeted injections: a very fine needle is used to inject small amounts into/around the bald patch.
- Multiple small injection points: this is normal for one patch.
- Short visit, but some discomfort: some people feel brief pain or stinging.
- Follow-up plan: your clinician decides whether to repeat based on regrowth and side effects.
Important: this is a clinician procedure. Do not attempt any “DIY” injection treatment.
Treatment schedule and timeline (realistic expectations)
Typical repeat schedule
Many dermatology sources describe repeating treatment every 4–6 weeks (sometimes monthly) while patches are active and regrowth is being monitored.
When regrowth may appear
- Some people may notice early regrowth in 6–8 weeks.
- Others may need longer, and many clinicians judge response over the first ~3 months.
When clinicians often stop or change the plan
If there is no meaningful regrowth after repeated sessions (often around 6 months), clinicians commonly reassess and move to a different strategy.
Side effects and risks (including dimples/skin thinning)
Common / local side effects
- Pain/stinging during injections
- Temporary dents/dimples in the skin (local atrophy/lipoatrophy)
- Skin color change (lighter or darker spots) in some patients
- Bruising/bleeding at injection points
Why dimples can happen
Dermatology sources note the injection should be placed in the dermis (not too deep), because subcutaneous placement increases the risk of skin indentation/atrophy.
Infection / severe reactions
Serious complications are uncommon in localized treatment, but infection and strong local reactions are possible. Active skin infection at the site is a reason injections should be avoided until evaluated.
Special note for eyebrows/beard
Intralesional steroid injections can also be used in selected eyebrow or beard alopecia areata cases. However, the eyebrow area requires extra care. Patient guidance sources note special caution around the eyes because excessive injections can increase the risk of local complications (including skin thinning, and glaucoma concern in the eyebrow region).
If you lost eyebrows/eyelashes or have widespread scalp loss, a dermatologist may discuss other/additional treatments depending on severity.
Eye-area guide: If alopecia areata affects the eyebrows or eyelashes, read: Alopecia Areata in Eyebrows & Eyelashes: Care Guide (diagnosis-first approach, eye-area precautions, and treatment options).
When injections are not enough (escalation)
If alopecia areata becomes extensive (many patches, total scalp loss, or body hair loss), patch-only injections are often not enough as a main treatment. AAD and other dermatology references discuss options such as:
- Contact immunotherapy (weekly in-office treatment in many protocols)
- JAK inhibitors for appropriate severe/extensive cases (clinician-directed, with safety monitoring)
- Combination plans (for example, injections + topicals/minoxidil in selected patients)
Read: Alopecia Areata Treatment: First-Line Options.
When to stop and seek care
- Rapid spread to many new patches
- Severe pain, burning, pus, or crusting (possible infection/another diagnosis)
- Deepening skin dents or marked skin thinning after injections
- No visible response after repeated sessions (discuss treatment escalation)
- A child with patchy loss plus scale/black dots (rule out tinea capitis)
FAQ
Are steroid injections the best treatment for all alopecia areata?
No. They are most useful for small patchy alopecia areata. Extensive disease usually needs a different or broader treatment plan.
How often are steroid injections given for alopecia areata?
Many sources describe repeating treatment every 4–6 weeks, depending on response and side effects.
How long until I know if they are working?
Some people see early regrowth in 6–8 weeks, but many clinicians reassess over the first ~3 months. If there’s no improvement after repeated treatment (often around 6 months), the plan may be changed.
Can injections leave dents in the skin?
Yes, temporary dimples/indentations can happen. This is a known local side effect and is one reason correct injection technique and follow-up matter.
