Last year, someone on this Board (can't remember who) was experiencing a significant amount of shedding. Someone suggested for a remedy the Motions CPR (Critical Protection & Repair) Hairdressing with tea tree oil. She used it and reported back that the shedding was immediately stopped. I used it for my own shedding and got the same result. The Motions CPR stopped the shedding in its tracks.
Also, I went on vacation without my Surge 14 Plus and I had a lot of shedding. When I got back, I sprayed my hands with the Surge and worked it through my hair. Shedding immediately stopped. Afterward, I realized my hair was protein deficient and it was just a matter of treating my hair with protein conditioners such as Aubrey's GPB. However, I was careful to Not Overdo the protein infusion.
