I have to wear human hair extensions for medical reasons. I buy the
"best" quality but really have trouble in keeping the hair beautiful
and tangle free (though I follow all instructions.) I suspect that the
manufactuers are less than forthright in how to "care" for the hair
b/c it is a commodity that is continually replaced. My question is:
any advice on products (especially silicone-based) or tips on how to
keep the extensions healthy. I am caucasion, can not use an oil-based
product and tired ! of spending 100's each month to replace a new
weave. Thank you in advance. M

This may sound strange, but a friend who uses human hair extensions
tells me that the best product she has found for detangling,
smoothing, and adding shine is Equinique Smooth-Shine Detangler, which
is designed for grooming horses:
