Honestly, I think it depends on what side of the 'fence' you sit on, and even under those circumstances, there appears to be some fairly 'grey' areas. LOL...
I'm not an expert on this and maybe someone else will elaborate. However, I have lurked long enough on this forum to know what the hot topics are and this in one of them. But back to your question...
I have no strong view one way or another on this topic so I will simply 'summarise' the different points I have heard - both for "heat training" and "heat damage". I also summarise
my understaning in
italics and
colour.
HEAT TRAINING
View #1:The constant use of (high) heat to gradually loosen your texture over time.
This view point generally doesn't agree that the hair is 'damaged'.
View #2: The frequent use of heat over time to 'train' your hair to straighten easily/with less effort over time.
Just like the point above, the general consensus of this view point is that the hair isn't damaged.
View #3: There is no difference between heat training and heat damage - they are one and the same.
I don't think I need to elaborate because this view point sees DAMAGE DAMAGE DAMAGE
HEAT DAMAGE
View #1: When heat usage (either direct or indirect heat *even this is debated but I think most people agree that it's
direct) causes the curl pattern to loosen.
Very frequently, the person complaining of heat damage will also report that his/her hair is limp, dry, with lots of split ends, prone to breakage, etc in addition to the aforementioned point. Some people in this category will consider cutting the damaged pieces or completely cutting off the hair depending on how much 'damage' he/she believes is done.
View #2: When heat usage causes the curl pattern to loosen but not enough to cause the hair to be in the state/condition mentioned above.
Usually in this case, the person may report that frequent deep conditioning and protein treatment helped restore the curl pattern (or at least to some degree).
View #3: People who claim their hair is 'heat trained' have damaged hair and they simply refuse to accept it as that. Even if their hair grows long, it is still damaged because the bonds of the hair have been broken.
Again, no need to elaborate here.
Well, have I missed anything? I really hope this thread doesn't cause any furore because I think the OP is truly just curious. I have summarised the points based on the general discussions. Please feel free to add/take away from what I've said.
NB: I will simply ignore any personal attacks as I do not feel like anything I have said is 'personal' to anyone
