  3. Great info, as usual, Sunshyne! Not only do we find out what to look for but we know why. Helps us to make informed decisions about our hair products.

  4. Your welcome ladies. LaQT that is exactly why I'm doing it. I feel like knowledge is power and it's good to know what you're putting in your hair.

  5. Hey Sunshyne love the site. Just found it late last night. I have a blog of my own about natural and organic skin care products. I was doing research on "Siloxane" and 'they' did animal test that revealed this was linked to tumor formation, endocrine disruption, and skin irritation @ moderate doses. then I learned that Proctor and Gambles' Pantene conditioners line dropped cyclopentasiloxane as one of their ingredients replacing it with bis-amino dimethicone. Let me know what you think about this. Love your site girl. Keep in touch. What you say is DEAD ON.
    My best, Lynn
    I want to link to you through my site.

  6. @ Lynn - Hey Lynn thanks for the headsup!!! I will definitely look out for it in my products and try to eliminate it. Thanks for visiting and for all the love.
