I think finding time is a massive factor, and you need to work out ways of finding the time for you.
Some of the things I have learnt that have worked for me:
Find a hairdresser that does late appointments. I have highlights and a cut at 7pm. Means that DH is home by then to look after the DC's.
Use the DC's bath time to do some things. So whilst they are in the bath, I tidy my eyebrows, paint toenails etc, take make-up off, put a 5 min face mask on. Keep it all to hand in the bathroom and it makes it really easy.
Think about using services near work rather than home. I get my eyebrows threaded in a place near wear I work. Much easier to pop in for 10 mins on the way home, than organise the time with the DC's etc.
I have a really pared down make-up bag for every day. All the other stuff that I might use goes into a big bag. Otherwise, its just my foundation and primer, bronzer, eyeliner, mascara and lip gloss. Makes putting make up on really quick.
Also if you have reasonably thick hair, invest in a good hairdryer. I have a Purlux. Was ££ but worth every penny as it takes 5 mins to dry my hair with it. It has been a life saver.
