Greetings, its ironic I just used this conditioner today. I have been experiencing a lot of breakage over the last few months and I've used all types of deep conditioners that were not working. I used CPR in the past with good results, but had to stop because I used it so much that my hair became brittle and would break anyway. Tonight I was so sick of feeling my hair break, and I remembered I hadn't used CPR in at least 6 mos, I thought I;d try it and almost immediately my hair stopped breaking. I could even comb through my entire head and no problems. so I highly recommend it BUT I would only start using it about once per week for about a month, and then drop down to once per month. Like I said, you will clearly see a difference, and your hair will likely grow faster because of it, but if you use it non-stop you will only end up with more breakage. Also, make sure to do a moisturizing condtioning rinse after you use it since CPR is a protein based conditioner. Tonight I used the Garnier Fructis, and Mane & Moisturizing Conditioner. Hope this helps.
