Thank you for getting in touch about our Herbal Essences Smooth Rose Hips Conditioner. We're deeply sorry to hear that your hair fell out in clumps. That's definitely not the kind of experience we want you to have and we understand how upsetting it can be. We appreciate your concern and want to assure you that our hair care products do not cause or speed up hair loss. A great deal of work has gone into the development and testing of all our products to ensure they are safe for use. Additionally, we have extensive quality controls in place and our products are used by millions of people every year. Hair loss is normal and is a continuous process. If you're experiencing extensive hair loss, we recommend speaking to your doctor. Still, to make sure your comments get the attention they deserve, we'd like to collect some additional information from you. Be assured that the details you provide will be shared with both our Safety Team as well as the rest of our Herbal Essences Team. Safety is our top priority and all of our products have been thoroughly evaluated to be safe when used as directed. While all our ingredients are thoroughly evaluated to be safe and effective when used as directed, we recognize some people may have personal sensitivities and cannot tolerate a particular ingredient or formulation. If you haven't already, we recommend discontinuing the use of the product. If you still have any remaining, we ask that you keep it on hand in the event we may need to retrieve it. When you find the time, please give us a call at 1-855-236-3327 or email us through our Contact Us Page so we can assist you further.
