When you're going on holiday, the last thing you want to worry about is how your hair is going to look in pictures.
But unfortunately, the humidity in many hot countries can wreak havoc on our locks and brings to mind the image of Monica from Friends trying desperately to tame her frizzy mop of hair.
Even in the UK, the recent bout of warm weather may have made your hair frizzier than normal. Thankfully, there are some ways to help smooth it back down again, and they'll leave you looking your best again.
Ghanima Abdullah, a cosmetologist at therighthairstyles.com, says that certain hair types are more prone to frizz, but there are ways in which it can be tamed.
She said: "Dryness is the main cause of frizzy hair; however, fine hair is more prone to this issue. Dryness can happen because their natural sebum doesn't always reach down to the tips of the strands.
"Any lack of moisture in the hair causes frizziness as the hair is then looking to absorb moisture from its environment. So when it's humid outside, there is more moisture in the air.
"Humid climates tend to make frizzier hair, as the atmospheric moisture exceeds that of your own hair."
Frizzy hair is never fun to deal with, but there's one key thing that we must be doing in order to help minimise the problem - and that's keeping our locks hydrated.
Using hair masks frequently is a good way to do this, as they can help to protect against any moisture that may be lost to the humidity.
Ghanima explained: "Using an overnight hair mask of coconut or olive oil will help prevent frizziness because the oil weighs down the hair shaft so it cannot stick up. This is the best treatment for curly and coily hair textures."
There are so many hair masks out there that it can be difficult to know which ones to go for when shopping around.
Ghanima says that it's worth taking a good look at the packaging as there are some key ingredients that work to prevent frizz and keep hair looking healthy and shiny.
She said: "For people with frizzy hair, using products containing silicone is a good practice to help lock in moisture. However, this is only a temporary solution and will not hydrate the hair from within.
"To properly care for frizzy hair, one should look for hydrating ingredients like aloe vera, agave, flaxseed and glycerin when selecting hair care products.
"A deep conditioning mask should contain at least one of these ingredients to effectively target dryness and smooth out the appearance of frizz."
There are also a few thing that we should try and avoid doing to our hair when it's hot out, as it can draw even more moisture out from our locks and make the frizz worse.
Blow-drying or using heated tools are two of the worst culprits, according to Ghanima.
But if you can't forgo these, it's important to use a good heat protectant and a deep conditioning treatment beforehand, as this can help to lock in moisture and keep frizz under control.
