    Thank you for your input, very much appreciated. I do have paraben as preservatives.
    The current pH of the shampoo is 4.7-4.8 (with 2% TEA) and the viscosity is adjusted at 2000-5000 cP with 1.5% NaCl), while the inspiration shampoo has the pH 5 and the viscosity 1500 cP.

    Glad to see people are still using time-tested parabens.I hesitated to recommend them but a good fit for your system.
