Reta and hair loss.

Summary

Does retatrutide cause hair thinning or loss during use?

Users report noticing thinner hair after shaving, with some linking it to large caloric deficits rather than the drug. Others say they experience no loss at all, while a few note slower growth rates that they find convenient. Similar effects appear with related compounds like Tirz for some people.

What this discussion establishesWhere people disagree

Whether the medication directly triggers deficiencies and hair changes or if diet alone is responsible.

Nothing here is advice.

Three months ago I shaved my head and everything looked fine. I shaved again yesterday and now the top looks thinner. Has anyone seen their hair return after stopping reta? It used to be thick and full but now it's sparse. I figure the big deficit is behind it, but I didn't expect this.

The issue isn't from retatrutide but comes from running a large deficit and eating a diet low in nutritional value.

I take twenty vitamin and mineral supplement pills every day and have never lost any hair. Reta can cause deficiencies very easily though.

I skipped Reta completely yet Tirz triggered major shedding from my scalp.

Even I experienced no losses whatsoever. After starting these compounds my hair grows quicker and looks a shade darker.

My scalp's gotten so bare these days that I end up buzzing it smooth as a habit. Yet after starting this, the growth rate seems reduced enough that I don't need to repeat the process quite as much, and that's turning out handy in my case.

Could you say whether you're male or female and how old you are? Women using GLP medications often mention quite a bit of hair thinning or loss. Around age 40 and beyond, perimenopause can also thin hair through falling estrogen levels even without any GLP. I'm a 49-year-old woman who shed 30-40 percent of my hair across the one to two years I took tirzepatide while dropping most of my weight, about 95 pounds. The shedding ended once the fast weight drop ended. Because of my age I don't expect the hair to regain its former thickness.
