Hepl!! Protein treatments vs Henna

I love the results of Henna!! The last time I henned was around october. Things have started to pick up and get buzy and I haven't had time to do the henna process. The result was shedding and much hair was coming out. Thanks to CN.com community and youtube.com I kept up my new and improved hair regime (day/night). 1. Once I start to henna again, will the protein treatments harm my hair?

-P.S. I used Aphogee two-step protein treatment about 3 days ago. It was not as harsh or dry as the henna is on my hair This stuff stinks to the highest of heavens!!

Henna mimics a protein so doing protein on top of henna may result in hard feeling hair. Be sure to use a good moisturizing conditioner after the henna.
