One of the most common reasons people abandon hair loss treatment too early is the dread shed. You start minoxidil, finasteride or another treatment and within a few weeks your hair seems to be falling out even more. No doubt it’s alarming and feels like the treatment is making things worse. So for many people the natural urge is to stop. However, stopping could actually mean walking away from a treatment that was actually starting to work. The dread shed is a well-recognised phase of many hair loss treatments and in most cases it’s temporary. Unfortunately, not every increase in shedding after starting treatment is due to the dread shed. In this article we explore why the dread shed happens, which treatments can cause it and how long it lasts. We’ll also review when shedding might be a sign that something is wrong and what to do.
What is the Dread Shed?
The dread shed is the informal term for an increase in hair shedding that can occur shortly after starting certain hair loss treatments. It’s sometimes called treatment-induced shedding or initial telogen release. To understand why it happens, it helps to know how the hair growth cycle works. Hair follicles cycle independently through growth (anagen), transition (catagen), rest (telogen) and shedding (exogen) phases. At any given time, around 85-90% of your scalp hairs are in the growth phase and 10-15% are in the resting phase. This means that they are going to be shed. When you start a treatment that stimulates hair growth, it can push resting follicles to re-enter the growth phase earlier than they would have naturally. However, before a follicle can start producing a new hair, it has to shed the old resting hair first. When many follicles do this at roughly the same time, the result is a temporary but noticeable increase in shedding.
This key point that gets lost in the anxiety is that the hairs that fall out during a dread shed are hairs that were already in the resting phase. Essentially they were going to fall out anyway. The treatment hasn’t caused new damage or worsened the hair loss. It’s just accelerated the turnover of old hairs to make way for new growth. The shed is effectively a sign that the treatment is activating the growth phase of the hair cycle.
Which Hair Loss Treatments Can Cause Increase in Shedding?
The dread shed is most commonly associated with minoxidil. This is because minoxidil directly stimulates follicles to re-enter the growth phase. Both topical and oral minoxidil can trigger shedding but it may be more pronounced with oral minoxidil. Minoxidil-related shedding typically begins 2-4 weeks after starting treatment. However, minoxidil isn’t the only treatment that can cause early shedding. Other hair loss treatments that can cause the dread shed include:
- Finasteride and dutasteride: These DHT blockers work more gradually than minoxidil by reducing DHT-driven follicular miniaturisation over time. Some people report increased shedding in the early weeks but it tends to be less dramatic than with minoxidil. However, these treatments work more slowly and through preventing hair loss. As such you shouldn’t automatically dismiss early shedding on finasteride or dutasteride as dread shed to ensure that there isn’t another cause.
- Spironolactone: This is an androgen receptor blocker which is sometimes used for female pattern hair loss. Spironolactone can also cause a transitional shedding phase.
- Tretinoin: When used as part of compounded hair loss formulations, tretinoin can in directly contribute to temporary shedding. This is because it increases cell turnover in the scalp which exfoliates the skin and boosts the absorption of actives like minoxidil.
- PRP therapy: Some patients experience a brief shedding phase after PRP injections as the growth factors stimulate hair follicle activity.
In multi-ingredient treatments where several actives are combined, the likelihood of an initial shed may be higher. This is mainly because more follicles are being stimulated through different pathways which tends to increase response.
What Does a Normal Dread Shed Look Like?
It can be quite hard to know whether you’re experiencing more shedding when you start a new treatment, let alone if it is normal dread shed or not. However, the typical treatment-related shed has some specific features that can help distinguish it from other types of hair loss:
- Timing: It usually starts within the first 2-6 weeks of treatment. With minoxidil specifically, 2-4 weeks is the most common window. If increased shedding begins months after starting treatment, it’s less likely to be a straightforward dread shed and may indicate another cause.
- Pattern: The shedding is usually diffuse and spread across the scalp rather than concentrated in patches. You may notice more hairs on your pillow, in the shower and on your brush. However, you shouldn’t see sudden bald patches appearing.
- Duration: Most treatment-related shedding settles within 4-8 weeks. Some people experience it for a bit longer but if it’s still clearly worsening after 3 months or there’s no sign of improvement, it may be something else.
- Scalp condition: A normal dread shed isn’t usually accompanied by pain, burning, heavy scaling or obvious inflammation on the scalp. The hair falls out but the scalp itself should look and feel relatively normal. If it doesn’t then there may scalp inflammation or infection causing the hair loss.
When Should You Worry About Increased Shedding?
Not every increase in shedding after starting treatment is normal. so whilst it’s important not to lose your never during the dread shed period, it’s also crucial not be too complacent. Signs that increased hair loss may not be the dread shed include:
- Timing doesn’t fit: If shedding starts long after starting treatment (e.g. several months in) then it is unlikley tobe the dread shed. Same is true if hair loss coincides with another trigger like illness, major stress, crash dieting, surgery, a new medication or a hormonal change (such as postpartum or perimenopause). In both these case, you may be dealing with telogen effluvium rather than treatment-related shedding. It’s also important to be aware that the two can overlap. For example it is common for women to have female pattern hair loss and telogen effluvium at the same time.
- Pattern isn’t diffuse: If you’re developing distinct bald patches rather than generalised thinning, this could suggest alopecia areata or another condition. These require urgent investigation as they may need a different treatment approach.
- Scalp is symptomatic: Significant pain, burning, itching, heavy scale, redness or pustules alongside shedding may indicate scalp inflammation, contact irritation from the treatment itself or an underlying scalp condition.
- Shedding continues: A dread shed should be a phase, not a permanent state. If you’ve been on treatment consistently for 6+ months and you’re still clearly losing ground with no sign of stabilisation, the treatment may not be working for you. There might also be another cause of the increased shedding.
- There are other symptoms: If you have significant fatigue, weight changes, feeling unusually cold or changes in your skin and nails, then you may have an underlying condition making hair loss worse. It’s worth seeing your family doctor and getting blood tests for thyroid function, iron levels and other nutritional markers.
How to Get Through the Dread Shed
Probably the most frustrating part of the dread shed is that the timeline for improvement doesn’t match the timeline for shedding. So whilst you may notice the shed within a couple of weeks of starting treatment, visible improvement in hair growth typically takes 3-6 months. That gap between “it’s getting worse” and “it’s getting better” is where most people lose their nerve and abandon treatment. The most important thing is to keep using the treatment consistently per your doctor’s advise. Stopping and restarting creates an unstable pattern that makes it very difficult to judge whether any treatment is actually working. Here are some practical tips to help deal with the dread shed:
- Set realistic expectations: Know that an early shed is a possibility before you begin treatment. If you’re mentally prepared for it, you’re far less likely to panic and stop.
- Take baseline photos: Photograph your hair in consistent lighting before starting treatment and then at monthly intervals. Photos are far more reliable than day-to-day perception because you can’t objectively judge your own hair in the mirror every morning. Over time, photos show trends that daily anxiety hides. Your doctr can also review them and give objective advice.
- Don’t add multiple new products at once: If you start treatment and immediately add a new shampoo, a supplement, a scalp serum and a microneedling routine at the same time, it is hard to know what is helping and what isn’t. Start your core hair loss treatment first and optimise your hair care routine in stages.
- Be patient with the timeline: Most hair loss treatments need 3-6 months of consistent use before you can meaningfully assess their effect. Some take even longer. Judging finasteride after two weeks or minoxidil after one month isn’t giving the treatment a fair chance.
- Seek a review if the pattern doesn’t fit: If there are any red flags or you’re worried it isn’t the dread shed, don’t be complacent. Get a proper medical assessment to make sure there isn’t anything else.
Does the Dread Shed Mean the Treatment is Definitely Working?
Sadly this isn’t necessarily the case. However, it’s a positive sign. An early shed that fits the expected timing and pattern usually indicates that the treatment is acting on the hair cycle which is what you want it to do. However, the shed itself isn’t a guarantee of good results. You can have a shed and still find that the treatment doesn’t produce the regrowth you were hoping for. The reverse is also true. Some people respond well to treatment without experiencing any noticeable early shedding at all.
The best way to understand the dread shed is as a transition phase. It’s the hair cycle clearing out old resting hairs to make room for new growth. Whether that new growth is strong enough to produce a visible cosmetic improvement depends on many factors. These include the stage of miniaturisation, the underlying cause of hair loss and how consistently the treatment is used. Multi-agent treatments such as combining a DHT blocker with a growth stimulant minoxidil may also optimise chances of success.
The dread shed is one of the most psychologically difficult parts of starting hair loss treatment. Seeing more hair fall out when you’ve just begun treating the problem feels completely wrong. But in most cases it’s a temporary phase that reflects the treatment shifting the hair growth cycle rather than causing new damage. The key is knowing what a normal shed looks like and being patient enough to let the treatment work. It’s also vital to recognise when the pattern doesn’t fit and get a proper review.
