I recently received the Irresistible Me Diamond Hair Styler* and have been giving it a try over the past couple of weeks. Normally I would just use this cheap hair straightener that I've had for years, but after using this I think investing in a professional flat iron is definitely a good idea. A little bit about the product - it has some really cool technology that prevents damage to your hair. The plates self-adjust to provide the perfect amount of contact between your hair and the plates so that it doesn't pull the hair, and the temperature adjusts itself as well. It has tourmaline technology which is a semi-precious mineral and it's embedded into the iron which is something I had never heard of before.
You can set the temperature yourself as well depending on how thick your hair is and it heats up extremely quickly - great if you're in a hurry! I find that I only have to go over my hair once or twice and it's perfectly straight. As you can see in the before photo, I do have quite straight hair naturally, but it tends to get a bit wild and frizzy due to the amount I've dyed it, and after using the iron it looks really nice and healthy! You can also use it to do different styles with your hair such as loose curls/waves, but my hair doesn't really cooperate with those types of styles so I can't say much about that. It retails for $149 but you can get 20% off your first order if you visit the website.
