Help me with curly straight hair - photos included

[CurlyNStaight]

All my life, I've been fighting with a hairdryer to try and straighten my hair. It looks nice and smooth when I'm done, unless the wind blows, or it's slightly damp, in which case it becomes extremely frizzy at the sides and curly underneath, particularly at the face of my neck.
Of recent years, it has become apparent that many curly haired people are trying to be straight head and should go with the flow. However, the room I have is that the back of my head goes perfectly, but the front is terrible! I cannot seem to help that part to curly. It's like I've got two people's heads of hair, and the front is straight and the back is curly!

My question is… How do I get the side parts to merge naturally with the rest? If I tried to scrunch it with hair products, it looks like a terrible tight, perm perm, and if I leave it to itself, it looks like I have straightened it and forgotten to straighten the rest, i.e., it looks completely mismatched and to be quite frank messy, as though I haven't bothered.

What do I need to do? As you can tell, I'm not brilliant with hair!

If you're using a hairdryer use a diffuser attachment and try doing it with your head upside down, pushing the diffuser bowl upto the roots and when you're 3/4 dry finish with the coolest setting so the curls don't drop. Don't blow-dry until bone dry either or the ends will frizz, let it be ever so slightly damp when you finish.

Layers round your face could help. When it's cut to all one length the hair from the top of your head is twice as long as the hair growing from the nape of your neck and the extra weight pulls it straighter. It probably does have a slightly different curl pattern in places though, this is normal (and a challenge). It does look fine as it is but it's you who needs to be happy with it, so make some changes if you're not

Thank you all for your replies and sorry I didn't come back sooner.

You've all been so positive! I’ve been using Aveda be curly but find it makes my hair feel dry. I normally use Aveda damage
Remedy and if I try to use that as a leave1in conditioner I can forget curls. So it really is to do with how I treat the hair. The trade off is I'm loving not using heat appliances and even though I feel more scruffy I feel more natural and don't care if the wind blows my hair as it's already a mess!

I found some website and tutorials and am so surprised there's a whole world when it comes to hair, grading the curls, different techniques to employ to get the best of the curl. I'm not sure I can even work out what grade my hairs is (2a or 2b), and can see it will be a lot of trial and error but the other thing is to stick with it to allow the hair to 'learn' a different way.
