Best Shampoo for Thinning Hair: Doctor's Choice

Hi everyone,

As a Doctor and a apart of the Mayo Clinic community for 7+ years, I usually try to share things that directly connect with health and wellness. Recently, a lot of colleagues and community members have been asking about thinning hair which is not just cosmetic, but often tied to stress, nutrition, and overall health.
I took some time to read through dermatology resources, check patient reviews, and compare ingredient safety. I didn’t want to just throw random names out thinning hair can be a sensitive subject, so I picked products that are gentle, effective, and aligned with good hair care science.
Here are two shampoos that really stood out:

1️⃣ R+Co Dallas Thickening Shampoo (https://www.amazon.com/dp/B017GGC9BI?tag=healthline018-20&th=1 ) – Known for giving instant volume and thickness to fine or thinning hair. Lightweight formula, doesn’t weigh the scalp down, and many users notice their hair feels fuller after consistent use.

2️⃣ Rosemary and Biotin Shampoo for Thinning Hair (for Women) ( http://www.amazon.com/dp/B01ENCBOA0?tag=healthline018-20 ) – Uses two powerhouse ingredients: rosemary oil, which has been studied for stimulating hair follicles, and biotin, which supports hair strength. Gentle enough for daily use and popular among women dealing with gradual thinning.

Both are safe, sulfate-free options that focus on scalp health — because that’s really the foundation for stronger hair growth.

I know hair thinning can feel frustrating and emotional, but even the right shampoo should be part of a bigger approach: balanced nutrition, stress management, and checking in with a dermatologist if it feels progressive.

Has anyone here personally tried either of these shampoos, or found something else that worked well for thinning hair?
