Yes, it warms! That's why I'm sure to only leave it on for 10 seconds.
I part my hair down the middle and apply it to one half of my head, rub it in while counting to 10, rinse it out and then do the same on the other side. I do it in the shower and it's so easy. I used it weekly when my hair was loose. I'm in a full PS now so I don't have access to my hair. I love it! And I can't wait to try it as my post-relaxer protein. And it smells good so I'm hoping it'll help with the post relaxer chemical smell.
I did a more thorough review in the Moremo thread about it. I'll try to find it and paste it here in case anyone is interested.
ETA: Here's the thread.

This is my review after my first use:
OK, so I washed my hair in the shower, parted my hair in two halves and applied the Moremo tx. Overall, I liked that my hair felt stronger immediately after applying it. It says to apply to "damaged" hair and my hair is texlaxed so I am always looking for
convenient ways to incorporate protein.
Immediate Pros:
-only have to leave on the hair for 10 seconds
-easy to apply in the shower
-hair felt stronger
-smells great
-possible to use in relaxing process to infuse protein back into the strands
Immediate Cons:
-it warms as it is left on and rubbed into the hair. I'm not sure about the science of it all but it definitely makes me want to quickly rinse it out, Lol.
-may not be able to be used during the relaxer/coloring process
I definitely want to use it more consistently before I give a good "review" on it. I am happy enough with how it went and how my hair felt afterwards to continue to use it.
