I’d snap a couple pics with wet hair if I were you because diffuse thinning can be hard to detect in the early stages.
Based on these pics, I’d say no. Though my hair looks okay on pictures when it’s freshly washed and dry but you can clearly see the diffusing when it’s wet.
Why do you think you’re thinning? Did you notice some more scalp, miniaturized hairs, loads of shedding? I wouldn’t worry about it too much because for 29 your hair looks solid mate!
