No rinse bath products?

I used a shampoo funnel when I washed my sister's hair. You can buy them online. I also used a sprayer hose that fit over the faucet for rinsing her hair. My sister was in her wheelchair with her back to the sink. I never had a problem washing her hair.

There are hair wash trays that can help you shampoo salon style, that's what we did

Thank you cwillie and grandma1954 for your answers. The bath aide noticed the build up this week too and said she would try to use shampoo next week to see if that clears it up. Mom won't get in the shower, so she'll have to bend over the sink and it won't be easy for her. I could take her to the beauty shop but I don't think the lady there would take enough time to clean her scalp very well.

When I use soap and water on Mom on the weekends, I use one washcloth for soap and then a fresh water-only one to rinse her, then change t he rinse wash-cloth after use in hopes of getting the residue off of her. Her skin is dry anyway so we always use lotion.

Anyone have any great ideas for lotion? Mom's skin is super-flaky and I've tried Aveeno, Vaseline extra dry rescue and some other super-moisturizing ones but they don't do all that great.

I've used coconut oil with a little scented oil for partial mini-massages too, but that doesn't seem to make any difference. Is it OK to use oil on her occasionally (maybe once a week)?

Thanks so much!

I used up my mom's leftover no rinse bath solution (the kind you add to water) on myself and it didn't leave any kind of residue, I did find it a little drying though so you may need to moisturize. In my opinion people using a sink/bowl of soapy water are often not rinsing with clear water to remove all of the soap residue.

As for the shampoo - I've read of people who swear by it and even prefer it to regular shampoo with water but for us it just didn't keep the scalp adequately clean over the long term.

I would ask the Home Health Worker to take a little more time and maybe if it is easy to use a wet washcloth and go over mom's head again with plain water.
It could be a residue from the product OR it could be almost what you would call Cradle Cap on an infant. Just a build up of oils. Sometimes it will clear up on it's own or maybe a gentle no tears shampoo might be what she needs once in a while.
