I have had my hair coloured dark brown since my 20s and last year noticed that the hairs around my face were breaking off where my grey roots stop.
This is now happening throughout. I have fine hair but lots of it so it’s not too noticeable yet, but I am worried! Why is this happening, and what can I do to resolve this problem?

I wouldn't worry too much as all humans lose up to 100 hairs per day. Lightening the hair does put it through more pressure and can exhaust it.
If you're going darker with your re-growth colour that should technically put your hair in to a better condition. Make sure you're having your colour done professionally and share this with your technician.
I would also suggest you try using Nioxin's scalp and hair shampoos. It's an excellent product which promotes a strong hair bulb at the root.

This is interesting. If hair is falling out then it would be a good idea that you go and consult your GP as this may be an indication of an underlying health problem. Hair loss can be the result of pregnancy, hormone disorders, under/over active thyroid and other issues.
Modern hair colourants shouldn't cause hair loss but if you are worried about it you should investigate whether there is an option to use a gentler colour line. Many manufacturers produce permanent dyes now without the use of ammonia for example L'Oreal INOA, Schwarzkopf Senea or Essensity.
