More hair in the shower drain, on your pillow, in your brush. It's alarming, but it's usually temporary.
This is called telogen effluvium — and understanding it helps.
Why this happens
Hair loss on GLP-1s is usually not a direct effect of the medication itself — it's a response to the stress your body is under from rapid changes.
Telogen effluvium happens when your body undergoes significant stress (rapid weight loss, calorie restriction, nutrient deficiency), which pushes hair follicles into a "resting" phase. Then, 2-3 months later, that hair falls out.
The timeline: Most people notice increased shedding 2-4 months after starting the medication or after significant weight loss.
What might be causing yours
"I'm losing hair in clumps when I shower or brush"
→ Classic telogen effluvium, usually tied to rapid weight loss from 2-3 months ago.
"My hair is thinning all over, not in specific spots"
→ Diffuse thinning is typical of TE and nutritional deficiency.
"I can barely eat and I'm not hitting protein goals"
→ Protein deficiency is one of the biggest drivers. Target: 80-100g daily.
"I'm also dealing with fatigue, brittle nails, or pale skin"
→ Signs of iron deficiency — get your ferritin checked.
What's actually helping people
Get Tested First
Before throwing money at supplements, ask your doctor for blood work. Ferritin should be 50-70 (not just "normal" at 15-20). Low B12 is a common but overlooked cause — some people see shedding stop within weeks of correcting it.
Collagen — The Gold Standard
Designs for Health Whole Beauty Collagen is the gold standard for hair loss. It contains Lustriva® (clinically proven for hair growth) and magnesium biotinate (40x more absorbable than regular biotin). If you buy one thing for hair, this is it.
B12 (if deficient)
Low B12 can cause hair shedding. Jarrow B12 Lozenges are sublingual, meaning they're absorbed under the tongue and bypass digestion. Some people see shedding stop within weeks of correcting deficiency.
Omega-3s
Nordic Naturals Ultimate Omega supports scalp health and reduces inflammation. High quality with no fishy aftertaste.
What else helps
- •Protein first — 80-100g daily minimum
- •Get ferritin tested — should be 50-70, not just "normal"
- •Be patient — hair has a growth cycle, recovery takes months
- •Slow your weight loss if possible — faster loss = more shedding
The bottom line
Hair loss from GLP-1s is usually telogen effluvium from rapid weight loss and nutrient depletion. It's temporary, but protein, ferritin levels, and Whole Beauty Collagen can help.
