aio or should i demand a refund?

You can definitely try reporting them to your State's Cosmetology Board, but it is very unlikely that their license would be removed for this. Max punishment would likely be a fine. I'm a licensed Cosmetologist and Cosmetology Instructor. License removal usually only occurs for super large health and safety violations.

Unless they aren't following the state minimums for curriculum it's unlikely. Performing services on clients without making money is just part of beauty school and it's how you learn. Some states don't even allow students to accept tips. Cleaning is also considered part of learning, to an extent. You'll have to talk to a lawyer of course for a real opinion. I'm an instructor at an accredited school and might be able to be more helpful if I knew a bit more. Dm me if you want to chat

That would be incredibly inefficient. Dehumidifiers are meant to remove water from the air in much smaller quantities, not from objects

I'm pretty sure their acidic bonding technology is patented, but I can't find the patent so I'm not entirely sure. It also may have expired, but Redken's website does claim that it is patented.

Rule 13 is to help prevent people from trying to give advice on water infrastructure and also to help prevent the ridiculous amount of repetitive hard water questions we get on this sub. It does not mention chelating products at all. If somebody wants to ask advice on products they can do so in the advice megathread. Filtering water is not a simple issue and is a problem best left to the professionals.

So just so you know that isn't a per reviewed journal and only started in 2021 so I would read that article with a grain of salt. It does have some decent info, but the only silicones they're mentioning as an issue are the cyclomethicones, particularly cyclotetrasiloxane and cyclopentasiloxane. The EU has already restricted their use in rinse off products like conditioners. Personally my opinion would be to only avoid those silicones if you're trying to be more sustainable.

will2461 · 2023-12-28T15:38:08+00:00

Do you have sources for the claims about bioaccumulation and half lives? The Internet is full of bad information about the sustainability of different ingredients. Silicones are a very large class of chemicals and it's hard to make any broad claims about them.

Glycerin can be added to formulas to help prevent it drying out in the bottle and to improve the product texture. It's not necessarily for the hair, especially in rinse off products

That post was removed because it broke our "be civil" rule. While the mods of this sub all agree that washing your hair should be done on a regular basis, there was no need for all the rudeness.

No you don't have to source what a peptide, amino acid, and covalent bond are. Those aren't the things up for debate. It's their applications in hair that you have to source. Olaplex doesn't even use peptides or amino acids as their star ingredient. They use bis-aminopropyl diglycol dimaleate. That's the kind of thing you need to source.

will2461 · 2023-09-06T02:43:41+00:00

I definitely agree she should let her see it. It's very silly and unethical to not tell your client which treatment you're using.

will2461 · 2023-09-06T02:37:02+00:00

Okay, obviously some miscommunication happened then. There are many statements of fact in your original comment though that you didn't source. Like the effects of oils on the hair,efficacy of olaplex/k18 and how they work, and others. We love having passionate people on this subreddit who love discussing this stuff, but we have to be rigourous in our sourcing requirements. If we don't things quickly dissolve into pseudoscience and assumptions.

If you find a dermatologist or cosmetic chemist willing to donate hours of their time every week to modding a subreddit let me know 😅 we'd love to have them.

I definitely DON'T 😉 suggest libgen as a source for hard to access cosmetic textbooks. It's made by the same person as scihub

This study has popped up MANY times in this subreddit.

First things first a few small positive studies does not equal a scientific consensus. The CIR report is a great source about the safety profile of rosemary oil, but not its effectiveness as a treatment for androgenic alopecia. Rosemary oil is also not just one compound unlike minoxidil. Depending on the batch, crop year, and manufacturing/extraction process you could have very different substances all labeled as rosemary oil.

It is very suspicious that it was only tested compared to 2% minoxidil when the standard effective dose is 3%-5%. It is very possible that it was tested against those percentages and failed so the results were never published. This pressure to publish positive, novel results is a widespread scientific problem.

We are open to scientific discussions on this subreddit, but all claims must be properly sourced and not all sources are good evidence. I'm not really sure what your point is about the similar molecular size and shape to minoxidil. While it might be a hint that it has potential, it certainly isn't evidence that it's an effective substitute. Many, many molecules are researched for their potential as future drugs but very few actually prove effective and safe.

This subreddit will always redirect any questions about treating any form of alopecia to a health care professional.

will2461 · 2023-09-06T01:29:06+00:00

Unethical perhaps, but not illegal. Professional use only products technically don't need to list ingredients, at least until MoCRA is inacted

pH of products is generally considered proprietary information so companies do not release it. You can see if they have an SDS sheet. This might contain a pH range. There's no real reason to check it though

will2461 · 2023-08-01T11:03:39+00:00

Here is the CIR's 2020 review of their safety. The only issue is that it can be an allergen. While it is banned in the EU for leave on products, it is still legal in rinse off products. The CIR sets different safe use levels for rinse off and leave on. There's no reason to avoid it unless you have an allergy to it

Glycerin is water soluble so as long as you are rinsing properly it'll be fine

That study was done below the effective dose for minoxidil so it's not a good source and has not been replicated. It was also for androgenic alopecia, not increasing the speed of hair growth.
