    TLDR Polisorbate 20 is not suitable for curl creams due to instability.
    The pilot study on curl cream development highlights the unique structural and moisture challenges of curly hair compared to straight hair. Curly hair fibers vary in shape and are more prone to dryness and damage due to their lifted cuticles. The study tested various curl cream formulations, which ranged from fluid lotions to mousse-like consistencies, and found them mostly homogenous and easy to apply, with pH values between 5.09 and 6.97. However, formulations containing Polisorbate 20 showed instability under mechanical stress, indicating it is an unsuitable emulsifier for these products. Further research is needed to better understand curly hair structures and improve product formulations.

      Curly and wavy hair can make hair loss appear worse due to clumping, but using less product, shorter cuts, and leave-in conditioner can help manage appearance. Minoxidil and finasteride are considered for treatment, and some find that styling can hide thinning areas.
