Worth every penny! Best ever!

Absolutely the best heat protection. Don't let the cost detour you - it's literally worth it. It does NOT leave residue on the hair and keeps hair from breaking when flat ironing. Has a great scent. I HIGHLY recommend using the CHI Silk Infusion hair serum after - that really seals in the moisture and leaves the hair SILKY and NOT oily! You can get a full size bottle of the thermal protector for about $5 more elsewhere, so shop around but the product is worth every penny you spend. You won't be disappointed.

A must have if you use heat appliances on your hai

I bought this Chi 44 Iron Guard Thermal Protection Spray in the 2 ounce size to use for travel and it is TSA compliant to carry on the plane. I recently took a trip to another state to visit my daughters, and for me, this is a must have as this product works well at protecting the hair when using hair dryers and curling irons. I have the full size that I use at home. I use it all the time, on wet hair immediately after washing my hair and towel drying and before using the hair dryer and also as I use a curling iron, I spray each subsection of hair just right before I curl that subsection. This technique makes it a little damp, but when you put the curling iron, it doesn't make that sizzle sound, which is good because that could "fry" your hair. But I think that it is really helpful to spray it on each sub section prior to curling because that way, you know that each strand of hair that touches the heat appliance is protected and I feel like it helps hold the curl a little better. The nice thing is that you can keep this pump spray bottle to refill from your bigger bottle to always use for travel. I gave it a 3 for appearance because of the Chi brand uses a red bottle for a lot of their products and it's easy to pick up the wrong one. The scent is very light which for me, is perfect considering all of the products that I put on my hair with different scents can be a little overbearing. It is not sticky at all. This is a high-quality product, and I highly recommend it, so it is pricier than your average "heat protector", but definitely worth it.

Works Great

The Chi 44 Iron Guard is our favorite heat protectant. My daughter and I use this on our hair when styling and it works great. It doesn't make your hair sticky or hard.
