the consular period (as of 1799) is an area of major changes in the overall aspect of the french army – this will be gradual from 1800 to 1805.
there are no strict regulations – as the official regulation is and will remain the 1786 one until
1812. It is amended by various decrees, but also by regimental orders or
verbal orders.
to summarize for the cavalry:
- Hussars: they will gradually change from the slender cone-sized mirliton to the peak-less shako and then standard shako from 1797 to 1801. Busbie stend also to be small and slender..
- Chasseurs: the shako has replaced the helmet (tarleton) in many cases already in 1797-1798 – usually this shako is ornamented with a cloth flame.
- Dragoons: helmets have had peaks since the 1786 regulation, but in some instances it is not worn – the change, if any is in the overall style of the helmet which will become increasingly slender.
- Cavalry: this is where most of the change occurs – the 8th regiment had always worn cuirasses – it starts having helmets as of 1801-1802, and gradually this is extended to other regiments – by 1805, cavalry regiments have either become cuirassiers or dragoons
The above is just an overview – many regiments switched to another branch of service – like the 7e bis hussars which became dragoons
Hope this helps.
