Iâ€™ve been noticing some odd patterns of shedding recently â€“ it seems that one time Iâ€™ll wash my hair and Iâ€™ll have a relatively high shed the next couple of days, and the next time I wash it, the shed will be less. I didnâ€™t really think about it until I was in the shower last night and thought â€˜which shampoo is it today?â€™ I switch between two shampoos each time I wash my hair, and now realise that my shed is lower with an SLS free shampoo and higher with the shampoo which has SLS. This has been going on too long to be a coincidence. As a bit of background, Iâ€™m a very allergic person â€“ Iâ€™ve gotten worse as Iâ€™ve gotten older, and developed allergies to a whole series of products meaning I canâ€™t use a lot of creams and perfumes etc. Iâ€™ve undergone so many tests I canâ€™t tell you and there is so much I canâ€™t use. Most recently I have discovered Iâ€™m allergic to lanolin, which is a product they put in moisturisers and creams that makes them smooth and creamy. So could I also be allergic to SLS (which they put in shampoo to make it foam up)?! I wouldnâ€™t put it past me! I am not saying that shampoo has caused my hair loss â€“ I donâ€™t believe that for a minute. And I also doubt this would be an issue for people who arenâ€™t very allergic or sensitive to products like this, but in my case, I think that using this product could be making things worse. I will cut it out completely and see what happens. Do you all think Iâ€™m crazy or does this sound feasible?
