You think hair products are good for the environment?
Not necessarily. But instead of taxing the haircut itself, why not tax the specific product.
to take an example, in Mexico they'd introduced a sugar tax if I remember correctly. The problem though is that this sugar tax is not charged on sugar only but also on sugary drinks. Should the drink containing less sugar be taxed as much as the one containing more sugar? The solution would be to not tax the drinks at all and instead to just increase the tax on sugar producers at the source. This means that a beverage producer would have to pay more for the sugar he buys to make his beverage. This creates a direct incentive for him to either reduce the quantity of sugar in the drink or pass the extra cost down to the consumer in the price of the drink itself, not through a separate tax.
By taxing the drink itself, we eliminate the incentive to reduce the sugar content since the drink will be taxed the same way past a certain minimum sugar content regardless of how much sugar is added beyond that.
So instead of taxing the hair cut, why not tax steel? The steel producer would then have to include the tax in his overhead costs and so pass it down to the scissor manufacturer in the cost of the steel. The scissor manufacturer would be paying that tax indirectly through the cost of the steel it uses to manufacture the scissors and then pass that cost down to the barber who buys the scissors. This gives the barber an incentive to care for his scissors. The longer the scissors last, the less tax he pays.
The same can apply to other hair products. That way, the barber would have a direct incentive to cut back on more expensive products and so indirectly pay less tax. The less tax he indirectly pays, the less he needs to pass down to his client who wants to get a hair cut.
In the case of a VAT like the GST or HST, no such incentive exists since no matter how responsible the barber is, he'll pay the same tax anyway?
So let's introduce a tax on non-renewable resources and a sin tax, raise the taxes as high at the market can bear, and then scrap the GST, HST, QST, and other VATs.

If there's a harmful product in that, then tax that, not the hair cut itself.
Unfortunately, the GST is totally nonsensically indiscriminate in its application and therefore eliminates any incentive to promote responsible spending habits.
