My Work....

The Before. Yes this is all her natural hair nothing is added but products. I washed her hair with Redken Smooth Down Shampoo and Conditioner. I then placed her under the dryer for 30 minutes with Halo Clear Rinse to add lots of shine and also to deeply condition the hair. Really coarse and thick hair tends to be on the dryer side so moisture is key to getting smooth healthy shinny hair.  Lastly, before blow drying I sprayed It's A 10 leave in conditioner again for added moisture. 

The After, I gave her a hard press and added some Aveda Brilliant Shine Drops before flat ironing, for two reasons.
The drops protect the ends from heat and it adds a luscious shine with a light fragrance to the hair.
