This is kinda hard, but I think most of my products are replaceable. I try not to get too caught up, although I have my favorites that I LOVE (fermodyl 619 and Porosity control shampoo
)!
I am been burned too many times by discontinued favorites.
I think one thing I have trouble replacing is a leave-in. It has been hard for me to find something natural and moisturizing with too much buildup or oiliness. If Qhemet closes shop, I would be kinda messed up.
No luck yet, but I have already been on the look out for possible replacements - just in case. Hopefully it will never come to that, but I like to keep my options open.
