One quick check: spin the blade assembly by hand with the jar off - it should feel smooth; any gritty notchy feel or up/down play means the sealed bearing is shot and the whole blade unit should be replaced. Also make sure the retaining ring and gasket are snug and seated correctly, and look for hairline cracks in the jar base that can let the blade sit low and chatter on the drive. A brief half‑second blip of the base with no jar can help isolate it too - if that’s quiet, it’s the jar/bearing; if it still grinds, you’re likely looking at the coupler or motor fan/bearings.
Dry hair sucks and especially when it's breaking all the time. I went through that after dyeing mine too often, and money was tight too. So I started reading labels. Go for shampoos that are free of sulfates because those can dry things out more, and check for ingredients that hydrate like aloe or glycerin.
I also cut back on washing every single day, maybe every other, and that made a difference. Soft hair again? Yeah, it's possible. be patient.
