Be sure to treat her well and she'll last for years :)
How I care my unit: I only finger detangle (no brushing or combing).
Wash 2xs with warm water (I use the shampoo Mane Regalia provided) and then condition (with the conditioner provided).
I only use a water diluted conditioner (Treseme Moisture Rich) in a spray bottle as a leave in..along with a small amount of argan oil.
I've had my unit for 3+ years, but I don't wear her daily.
