Dryness is one of the most common side effects of regular blowdrying. As an antidote to the moisture-leaching effects of tongs and hairdryers, I recommend a weekly deep conditioning treatment. One of the best I’ve tried is New York-based colourist Rita Hazan’s Weekly Remedy Treatment (£34 for 118ml), a two-step regimen that takes 20 seconds to apply, rinse and be done with. A profusion of oils – jojoba, mirabelle, olive and moringa seed among them – adds immediate moisture and shine.

My regular use of styling products often leaves me with blocked follicles, which has had me reaching for Omorovicza Revitalising Scalp Mask (£55 for 200ml), a salicylic-acid-infused Hungarian moor mud treatment that clears follicles, allowing hair to grow undisturbed by impurities. It has a fine nozzle for tidy application to the scalp and contains menthol and camphor to soothe any itching or sensitivity.
As a preventative to naturally occurring mid-life hair thinning, I’ve been taking the vegetarian hair supplement Kansha Alchemy Good Hair (£40 for 60 capsules) for well over a year now. It contains more than 30 vitamins (including biotin), minerals and herbs that I’d find hard to integrate easily into my diet, and I’ve seen the benefit, as well as longer, stronger nails as a bonus.

Finally, to deal with frizz, particularly that caused by regular air travel, my newest handbag essential is Rosarco Milk Leave-In Conditioning Spray (£18.50 for 147ml) from clean hair brand Briogeo, which uses argan oil to restore moisture.
