If someone tells you not to use something, there’s probably a reason.

That became a problem during one teenager’s sleepover with her best friend of more than 10 years.

The girl regularly dyes her hair purple, so she mixes some of the color into her shampoo and conditioner to keep it from fading.

Well, before her friend showered, she told her not to use those products, but she never really explained why.

Her friend used them anyway, and with naturally light blonde hair, the purple color took almost immediately.

Read on to see what happened when her friend noticed.

AITA because my best friend of 10+ used my hair products hen I asked her not to and now her hair is dyed purple?

For context, I’m F15, and she’s F16. I chronically dye my hair purple, but to avoid damage, I use a semi-permanent dye.

I’ve put some in my shampoo, conditioner, and hair mask so it doesn’t fade super quickly.

The products are expensive, and I use my own money to buy them.

She tried to warn her friend before she ever took a shower.

Okay, so what happened is me and her were having a sleepover a few days ago. Usually, we sleep over at her house and not mine since her room is bigger, and so she hasn’t ever seen my products, which have hair dye in them.

And I use pretty good products (I forget what it is, but they’re L’Oreal in the purple containers), and they’re pretty good but kind of expensive.

When she showered, I asked her not to use my products, although I didn’t really give her a reason, which might’ve been where I was wrong. She asked why, and I said because they were expensive and “purple,” which was probably confusing.

Of course, her friend used the products anyway.

The products themselves are purple, like the colour of the shampoo before putting the dye in, so I doubt she noticed, but I meant purple because they have dye in them.

Well, she used them anyways, and now her hair is dyed purple. She has naturally very light blonde hair, and so the colour took very easily to her hair.

She blew up, screaming at me, calling me a **** and selfish, and said I did that on purpose to be a *****, but they only have dye in them for my purple hair.

Now, her friend won’t speak to her.

She started throwing stuff around my room, saying how I made her look like a *** worker “like me,” which hurt my feelings a lot.

She called her mum to pick her up at like 12 a.m. and hasn’t spoken to me since, except when she blew up my phone, saying I was a ***** and that she hated me, and she told me to “take a swan dive off the nearest building.”

I feel awful. I know I should’ve explained why I didn’t want her to use my products in a better way, but I wouldn’t have used anything of hers if she told me not to, even without a reason. I’m so upset. We’ve been friends since kindergarten, and I don’t want the friendship to end because of this.

AITA?

Wow! Imagine being that mad over something that will wash out.

Let’s see how the readers over at Reddit feel about this situation.

This person thinks her friend should’ve listened.

Her friend has no one to blame but herself.

She was told not to use the products, and instead of listening, she used them anyway.

But the way she acted afterward was much worse, especially after being friends for more than 10 years.

At this point, the girl should give her some space and seriously think about whether she wants to continue a friendship with someone who talks to her like that.
