How to change things on your dude?

I don't know about once a month - that sounds a bit too often, but it really is recommended to cut your hair every 6 weeks. This cuts off any split ends and damaged hair and generally gives a more healthy and robust look to your hair

You are right in thinking that face shape does play a role in choosing hair styles. Faces can be a whole range of shapes; round, square, oblong etc and different styles with flatter one face shape and potentially look terrible on another. So I would really advise you not to go for a 'one cut fits all' approach with your girls. Ask your hairdresser for some advice. You can even find sites on the internet now that allow you to upload a picture and then muck around with different hair styles so you can see how they would look on you.

For hair I would recommend to keep your hair long and layered.As far as clothing I would recommend loose flowy clothing and clothing that fits, and wear clothing and jewelry that draws attention to your favorite features. Horizontal stripes are usually better to avoid because they give an illusion of making people look wide

I once heard you can periodically spray "Spray Starch" on the baffles themselves to alleviate lint and hair buildup. If you can prevent the unwanted particles from building up on the baffles theoretically they should be trapped in the dryer's lint collector.

To all of you: adjusting the screws won't help, unless you screwed something up yourself, of course LOL The same problem bothered me a few years, and an hour ago I found out it could easily be a single hair stuck between the blades, thus separating them a bit. Get rid of it and the trimmer will probably work again. It can even get out spontaneously, which happened to me and kept me wondering what was going on.
P.S. DON'T lubricate unless you are required to (check your manual) The model I have (HC210c) does't need lubrication, I guess yours is similar to it. And remember that NOT every oily substance is a machine lubricant.
