My hair is so long it's currently getting stuck in my bra/handbag on a regular basis.
When it comes to styling; it feels like my arm may drop off before I've made it round all of my hair with a curling wand. So lately I've been experimenting with 'heatless waves' and a couple of easy, peasy overnight styles that result in the perfect/unperfect bed-head, loose waves - but with barely any effort. ('cause I'm a bit lazy like that).
I feel these work best with 90% dry hair, so ideally you've just washed it. Either let it dry naturally (as I did) or a quick blow-dry won't hurt. However I do sometimes just sleep with these in with second/third day hair to avoid complete mayhem in the morning and you still get a similar effect!
Simply tie your hair up into:
A high bun
The trick with this is get it quite high up on your head, then twist your entire ponytail right to the tip and curl it round on itself into a bun shape. Try keep your hair smooth so that it isn't completely frizzy in the morning! Secure with a loose/soft bobble or scrunchy, to avoid any kinks in your hair. Also if you have a fringe/bangs, leave them out... For obvious reasons.
A loose plait
I'm not very good at plaiting, but a simple loose plait will create nice (fairly tighter) waves while you sleep. The higher up you can start this the better - so you don't end up with half straight, half wavy hair!
A double bun (or Miley Cyrus)
Similarly with option one, this creates lovely loose waves but almost with double the texture, as you're getting two twists in, instead of one. Simply gather half your hair into a high pigtail and twist the whole thing (again, keep it smooth to avoid frizz) and clip/tie into place with a soft hair-tie. Repeat on the other side!
Then hop into bed and let your hair do the hard work!
My favourite is option one, as it's just so simple and you do get a really nice effect from it, plus while the weather is warm, I much prefer to sleep with my hair off of my face! So it's a win, win! Of course a little bit of taming & fussing is required the morning after, but generally this is how I've been 'styling' my mane lately (I can't wait to get it cut, asap!) Plus I also find that because my hair has dried this way, rather than using a tool - it actually lasts a lot longer and doesn't drop out throughout the day. Bonus!
