Actually, I think that this grief system is appropriate for any form of grief, including hair loss. You just need to adjust your perception to a person who is suffering from hair loss.
Denial: "This must be just Telogen Effluvium from the stress that I had at work/school." "I am not getting enough vitamins or nutrition." "My dad still has a full set of hair, I can't be balding." "I am too young to bald."
Anger: "Why me? I am still young; I shouldn't be balding." "My parents are to blame for bad genetics." "How come my grandfather/brother/dad still has their hair and not me?" "This is not fair."
Bargaining: "Please let me keep my hair until I graduate from college/marry a hot wife.
"
Depression: "None of the hair loss treatments are working, I give up." "Why bother going outside If I am going to be ridiculed/stared at?" "I feel so insecure about myself now."
Acceptance: "Hey, there are plenty of handsome bald people in this world." "I look decent shaved and don't have to worry about hair maintenance anymore." "Losing hair doesn't affect my health, it's fine."
Although, I understand that someone might be offended since this was originally for the terminally ill, this system can still be applied well to other forms of grief.
