please talk about the tricologist issue because people truly think they’re doctors 😭 not realizing they’re usually just a 6-12 week course with no regulations (that I know of? maybe i can be corrected there)

I use nizoral once a week. I have thin hair. my hair doesn't feel clean until I use it twice.

I always thought companies put that on the label so you would run out of product faster and have to buy more faster.

I shampoo twice because I wash my hair every three days and it’s full of oil and dry shampoo. If I don’t, my hair isn’t properly clean

if this is more recent it might’ve come from an interview in R29 or somewhere like that with a cosmetic chemist who talked about shampoo efficacy & how the direction to repeat was taken off when shampoo labeling got more crowded & standardized. she specifically said washing twice was better!!

what is your opinion on the this: we don't need to wash hair with shampoo , we only need to brush it and distribute the oils and that's it

also water hardness. the minerals in hard water interact with surfactants in a way that can make them less effective which means the same shampoo may not give the same results with different water.

Can you talk about castor oil? Is it helpful for anything really?

I have dry scalp and even drier skin. I shampoo once thoroughly, take my time make sure I get all areas of my scalp, rinse and hair mask for 5-7 min. That’s it. Most of you don’t need more than once. Jz use a clarifying shampoo once every 4 washes or so and you’ll be fine

Chemist here to say FACTS but also this is largely another clean beauty casualty because brands just don’t use surfactants like they used to lol

That idea came from manufacturers who wanted to maximize use-up rate.

hair stylist here! I 💯 agree! when clients ask me how often they should shampoo (insert eye roll)...when and if it's dirty boo boo. if you've got a $hit ton of product in your hair and your using a gentle shampoo and it doesn't take out all the gunk, wash it again. you can't fix it 🧐

Definitely agree! To add, i think because sulfates are generally avoided, i think people (especially those that live where there is hard water) find that the have to shampoo twice even with "harsher" shampoos like clarifying shampoos

Such an easy flow chart for me 😂: is my hair dirty? If so, wash it. After washing it is it still dirty? Wash it again. I agree the TikTok hair advice on here is cray

As a hairstylist I agree! Everyone's hair and scalp are different. We have to treat everyone's hair differently. 🥰
