I use a mixture of strip and hot wax for Hollywoods.
You can do a good intimate wax with strips but you must support the skin properly. The old fashioned way is to keep the knickers on and pull to each side, this really helps with supporting the skin. Also you have to train your clients to support their skin. If clients are used to strip wax it's ok - although in my experience of gaining clients from other salons, a lot of snapping occurs. I've had clients come to me who have never had their pubic hair removed from the roots before - they can't believe how much more long lasting my results are.
I'm a bit out of practise with strip wax around the labia tbh and I dont like to put too much strain on my wrists and thumbs, so I always hot wax in the g-string area. I use strip wax around the outside of an imaginary g-string, if that makes sense.
Have a look on Instagram and you tube for waxing videos. The outback Organics videos demonstrate the properies of thei wax rather than give you technique tips.
