The reason your curls are lasting is because the wand throughs out some serious heat - the hotter the wand the longer the curl will last - BUT, and it is a big BUT this will damage your hair and some of this damage will be irreversible. ...More >
I want to break this down for you; firstly to address the damage in your hair, then to prevent further damage and then look at curling wands that will produce great curls but wonít fry your hair.
1. Damage: I would recommend you use a collection of products that will improve the strength and general condition of your hair, look for products that contain wheat protein as they will contain essential amino acids to repair the structure of your hair and add much needed moisture. We use Electric Hydrate Shampoo and Conditioner as they are packed with wheat protiens and jojoba & meadowfoam to hydrate, repair and reduce breakage. Use a hair masque every seven to ten days to really nourish and condition - your hair will thank you for it! (top tip - apply your hair masque after your shampooing and then once you have rinsed off the masque apply your regular conditioner to lock in all the goodness - rinse and style as normal).
2. Damage prevention: If you take one piece of advise from this reply let it be this one: USE HEAT PROTECTOR. I canít stress how important this is when using heated styling tools. We use P4 Preparation Spray and we also love Kerastase Ciment Thermique. Go for the best your budget can afford.
3. Which Wand? We use Babyliss Pro wand - the great thing about this wand is has thermal control dial - allowing you to reduce the heat to prevent damage. I would look for a wand that has heat control and experiment using a reduced heat along with a great hold hairspray combined with using the products above and I guarantee your bouncy curls will be shiny and full of health in no time!
