A TikTok creator explains why hair continues to shed while using topical finasteride. We reviewed the clinical evidence to see if their explanations hold up.
What does this video actually claim?
@euroasian64 addresses why people still experience hair shedding despite using topical finasteride for hair loss. The creator suggests this continued shedding is normal and expected during treatment.
The video positions this as educational content for people concerned about ongoing hair loss while on therapy. It's framed as reassurance for users who might be worried their treatment isn't working.
The creator doesn't specify exact timeframes or mechanisms, keeping the explanation general. This type of content is common in the hair loss community where people often panic about initial shedding.
Does the science back this up?
Continued shedding during early finasteride treatment is well-documented in clinical trials. The landmark studies by Kaufman et al. (Journal of the American Academy of Dermatology, 1998) showed initial hair loss before regrowth in many patients.
Topical finasteride works by blocking DHT locally in hair follicles. Research by Caserini et al. (Skin Pharmacology and Physiology, 2016) found 0.25% topical finasteride reduced scalp DHT by 68% while maintaining low systemic absorption.
The shedding occurs because finasteride pushes weak, miniaturized hairs into telogen phase faster. These damaged hairs fall out to make room for potentially stronger regrowth. This process can take 3-6 months to show positive results.
What did they get right and wrong?
The creator correctly identifies that continued shedding doesn't mean treatment failure. Clinical experience shows many patients abandon effective treatments because of this initial phase.
However, the video lacks important specifics about duration and expectations. Studies show shedding typically peaks around 2-4 weeks and should decrease by month 3-4. Without these timeframes, viewers can't properly evaluate their response.
The creator also doesn't mention that excessive or prolonged shedding beyond 6 months might indicate treatment isn't working. Some patients are non-responders, and continued severe shedding could signal the need for additional interventions like minoxidil.
What timeline should you actually expect?
Clinical trials provide clear timelines for finasteride response. The Kaufman studies showed hair count improvements became visible at 6 months, with continued improvement through 2 years.
Initial shedding typically lasts 4-8 weeks with topical formulations. After 3 months, you should see shedding return to baseline or below. Visible regrowth usually appears between months 4-6 in responders.
If you're still experiencing heavy shedding after 6 months, that's worth discussing with your provider. Studies show 83% of men maintain or improve hair count with oral finasteride, but individual response varies significantly.
