Query: Disappointed

I usually only use conditioner on my hair the day after flat ironing, which isn't frequent. This conditioner doesn't work for me. My hair sheds when I wash it, but usually in long strands. When I use this conditioner, short pieces of my hair break off. My hair is pretty healthy, not color treated, minimal exposure to heat styling tools, and the breakage only occurs while I am applying and rinsing out this conditioner. The breakage does not occur on days when I only shampoo. Also, once my hair dries, it looks dull and flat, which again only occurs on days I use this conditioner. At first, I thought the breakage, dullness, and lack of body were due to my flat iron use, but I haven't used heat tools in a couple of weeks and decided to use the conditioner this morning and had the same problems. I'll be switching to something else.
