Dermatologist Summary

Hair shedding on Ozempic, Wegovy or Mounjaro is usually temporary telogen effluvium, triggered by rapid weight loss and eating less protein and nutrients. The most effective way to support your hair is to cover nutrition and scalp health together: get enough protein, fill vitamin and mineral gaps, care for the scalp daily and be gentle with styling. The MDhair GLP-1 Hair Support Kit puts the nutrition and scalp steps into one simple routine.

Quick answer: the 7 best ways to support your hair on a GLP-1, ranked

1. Use a complete GLP-1 hair routine (MDhair GLP-1 Hair Support Kit)
2. Put protein first at every meal
3. Check iron, vitamin D and thyroid levels with your doctor
4. Lose weight at a steady pace
5. Treat your scalp and strands gently
6. Protect sleep and manage stress
7. Track progress with monthly photos and stay consistent

Why do Ozempic, Wegovy and Mounjaro cause hair shedding?

GLP-1 medications don't attack hair follicles directly. They lower appetite, and the result is often fast weight loss with much less protein, iron and zinc coming in. The body treats this as a stress and moves more hairs into the resting (telogen) phase. Two to four months later, those hairs shed. This is called telogen effluvium, and it is usually temporary.

The ranked steps below address each cause. For more background, see Ozempic, Wegovy and Mounjaro Related Hair Loss.

1. Use a complete GLP-1 hair routine

Best for: anyone already shedding, or starting a GLP-1 and wanting to protect their hair.

The single most effective step is covering nutrients, protein and scalp care at the same time. The MDhair GLP-1 Hair Support Kit ($99 on Amazon) was built for exactly this:

• Restore Supplements: biotin, iron, zinc and B vitamins. Iodine-free, vegan and gluten-free. 1 capsule daily with food.
• Marine Collagen: amino acids used to build keratin, plus vitamin C and hyaluronic acid. 1 scoop in 8 oz of liquid daily.
• Restore Serum: copper peptides with saw palmetto, rosemary and pumpkin seed oil. 1 ml on the scalp daily, left on at least 4 hours.

Restore Supplements can be used with GLP-1 medications; consult your physician.

2. Put protein first at every meal

Best for: people whose appetite is low and meals are small.

Hair is made of keratin, a protein, so protein shortfalls show up in your hair. When you can only eat a little, eat the protein part of the meal first: eggs, Greek yogurt, fish, chicken, tofu or legumes. A collagen drink such as MDhair Marine Collagen adds amino acids without needing a large meal. Ask your doctor or dietitian for a daily protein target that fits your body and goals.

3. Check iron, vitamin D and thyroid levels with your doctor

Best for: anyone whose shedding is heavy or lasts longer than six months.

Low iron stores (ferritin), low vitamin D and thyroid changes can all add to shedding, and they become more likely when food intake drops. A simple blood test can find them. If you take any biotin-containing supplement, tell your doctor before blood work, as biotin can affect some lab results.

4. Lose weight at a steady pace

Best for: people losing weight very quickly.

The faster and steeper the weight loss, the bigger the shock to the hair cycle. If shedding is significant, talk with your prescriber about whether your dose and pace are right for you. Never change your medication without medical guidance.

5. Treat your scalp and strands gently

Best for: anyone in an active shedding phase.

• Skip tight ponytails, buns and braids that pull on the follicles.
• Use lower heat on blow dryers and irons.
• Choose a scalp-focused shampoo such as MDhair Regrowth Shampoo.
• Massage the scalp for a minute or two when you apply your serum.

6. Protect sleep and manage stress

Best for: people going through other big changes alongside weight loss.

Telogen effluvium is a stress response, and stress from many sources adds up. Regular sleep, daily walks and other stress-lowering habits support the whole body, including the hair cycle.

7. Track progress with monthly photos and stay consistent

Best for: everyone.

Hair grows about half an inch per month, so changes take time. Take a photo of your part and crown once a month in the same light. Most people see shedding settle within a few months, with visible density improving over three to six months. Learn more in GLP-1 Hair Loss: How Long Until It Grows Back?

Supplements vs. topical serum: do you need both?

	Supplements + collagen	Topical serum
How it works	Supplies nutrients and protein building blocks from the inside	Supports the scalp and follicle directly from the outside
Addresses	The nutrition gap caused by eating less	Scalp environment and strand strength
Best for	Low appetite, low protein intake	People who want direct, minoxidil-free scalp care

Bottom line: GLP-1 shedding has both a nutrition side and a scalp side, so using both together, as in the GLP-1 Hair Support Kit, covers the most ground.

Frequently asked questions

How can I stop hair loss on Ozempic?

Focus on the causes: eat protein first at every meal, fill vitamin and mineral gaps, and support the scalp daily. A complete routine such as the MDhair GLP-1 Hair Support Kit covers nutrients, protein and scalp care together. Talk with your doctor if shedding is heavy or lasts longer than six months.

When does GLP-1 hair shedding start?

Telogen effluvium usually starts two to four months after the trigger, so many people notice shedding a few months after starting a GLP-1 medication or after a period of rapid weight loss.

Does Mounjaro cause more hair loss than Ozempic?

Shedding on any GLP-1 medication is mostly linked to how fast and how much weight is lost, and to lower food intake. The same supportive steps apply whichever medication you take.

Will my hair grow back after GLP-1 shedding?

In most cases, yes. Telogen effluvium does not destroy the follicle. Once nutrition and scalp health are supported, regrowth usually follows over several months.

Is collagen good for hair loss on GLP-1s?

Collagen peptides provide amino acids used to build keratin and are easy to take when appetite is low. MDhair Marine Collagen also includes vitamin C and hyaluronic acid.

Should I stop my GLP-1 medication because of hair loss?

Don't stop or change your medication on your own. Talk with your prescriber, who can review your dose, pace of weight loss and lab work.
