Holidays and hot weather are brilliant for raising your spirits during summer, but they can wreak havoc on your hair – especially if it’s wavy, coiled, kinked or curly. Sun, sea and swimming pools – or all of the above – can leave your crowning glory looking frizzy and lacklustre by the time September rolls around. “Curly hair can be more fragile than straight hair because the cuticle layer remains more raised than it is on straight hair, which leaves it more vulnerable to breakage,” says Kevin Hughes, global artistic director at Moroccanoil. Plus, if your strands aren’t healthy and hydrated it’s harder to get that gorgeously glossy, defined look, because curly hair naturally tends to be less shiny. “When there are twists and turns in the hair shaft, it absorbs parts of that reflection, reducing some of the shine that we see,” Hughes explains. “This dullness is increased if the hair is damaged or distressed by UV rays, sea and environmental aggressors.” But it doesn’t have to be that way. Here are six expert-approved ways to rejuvenate curly hair… 1. Soothe your scalp “Curly hair has less moisture than straight hair because the oil from the scalp cannot move down the strands of hair as easily,” says Hughes. This problem can be exacerbated in summer if you’ve been sunbathing without a hat. “Occasionally I see dry or damaged scalp on clients who have braids and textured styles, as it is more exposed to the sun and subject to sunburn,” he says. Just as you would apply aftersun to parched skin and keep it covered, treat your scalp to a moisturising serum or mask and leave it on overnight. “I would be sure to use some aloe vera, apply to your scalp and wash less often to allow the natural oils to replenish and balance the scalp,” says Hughes. 2. Detangle knots “Healthy curls and coils are well-defined, springy and bouncy – lack of definition and tangles could indicate damage,” says Jennie Roberts, afro hair Expert at SheaMoisture UK. She recommends regularly detangling to “prevent knots and tangles from forming, which can lead to breakage. Use a brush or comb designed for curly and/or coily hair to avoid damaging the curls, kinks and coils”. Hughes suggests applying conditioner to wet hair before you wash it as an extra detangling step: “The conditioner will break down what is in the hair and rinse away with the conditioner, so the shampoo won’t make it worse than it already is.” 3. Bring back the bounce “Gently stretching a strand of hair should result in some level of elasticity without immediate snapping,” says Roberts. “If your hair breaks easily without any flexibility, it might be damaged.” From shampoo to styling, hydrating products are key for repairing your locks, says Hughes: “Look for ingredients that moisturise the hair, like panthenol and jojoba, as well as strengthening ingredients, like vegetable proteins.” Roberts adds: “Consider using a deep conditioning treatment at least once a week to maintain moisture levels.” 4. Avoid heat and chemicals “Minimise the use of heat-styling tools like blow dryers and straighteners, as they can cause further damage, especially in humid conditions,” says Roberts. Always use a heat protection spray, and if you’re planning a summer escape, try to resist the urge to book salon appointments for anything other than a trim. “Wait until you get home from holidays before you have any chemical treatments such as colouring, perming, or relaxing,” Roberts says. “As you’ll be able to assess the condition of your hair better – the heat and weather will just add to the damage.” 5. Revive your curls While it may be tempting to reach for a heat styling wand when you want to zhoozh up your curls, if you want to protect your locks, it’s better to use a gentle hair routine during the summer months. Starting with freshly washed hair, Hughes says: “Make sure to blot it dry with a towel, meaning don’t be rough with it, then spritz through a heat protection spray – this will be the last time you comb through your hair.” Next, he says: “Scrunch the hair from the ends up to the scalp with the palm of your hand, then use a diffuser to dry the hair – essential to keep from blowing the curls around and getting frizzy.” If you do have any frizzy areas, use a heat styler sparingly: “Use a curling iron the same size as your curl; pick up random pieces of hair and redefine the curl with the iron.” 6. Lightweight styling products “Choose lightweight products to prevent buildup and to avoid weighing down your curls in the humid weather,” says Roberts. “Hair butters and creams will melt, so water-based products are always advised.” This is particularly important for the final step in your styling routine. “Use a curl-enhancing styling product,” says Hughes, such as a mousse or cream, to scrunch and set your locks. “Don’t brush or comb through your curls after hair is dry.” Charles Worthington Moisture Seal Leave-In Conditioner, £8.99, Superdrug SheaMoisture Strengthen & Restore Hair Treatment Masque, £12.99, Boots Osmo Curl Revival Replenishing Cream, £10.99, Sally Beauty Briogeo Curl Charisma Rice Amino and Quinoa Frizz Control Gel, £21, Cult Beauty Moroccanoil Curl Defining Cream, £26.85

Have you got a favourite track? Well, it’s time to turn it up and enjoy the beat with a warm cup of coffee. Everyday pleasures like listening to music or sipping a cup of coffee can elevate brain activity, improving cognitive performance including in tasks demanding concentration and memory, according to a recent study. A group of researchers looked at a new NYU Tandon School of Engineering study involving MindWatch a brain-monitoring technology. MindWatch is an algorithm that analyses a person’s brain activity from data which is collected from a wearable device which can monitor electrodermal activity (EDA). EDA is a measure of electrical changes in the skin triggered by emotional stress, often associated with sweat responses. In the study, published in Nature Scientific Reports, participants were made to wear these skin-monitoring wristbands as well as brain-monitoring headbands to complete a range of cognitive tests. The tests were conducted while the participants listened to music, drank their coffee and smelled perfumes reflecting their individual preferences. These tests were completed again without any of those stimulants. Researchers found that both music and coffee significantly influenced participants’ brain arousal, and put them in a “state of mind” that could “modulate their performance in the working memory tasks they were performing,” the NYU press release says. The wearable device found that the stimulates specifically triggered increased “beta band” brain wave activity which is linked to peak cognitive performance. Perfumes also had a slight positive effect, suggesting to researchers that there is a need for further investigation. “The pandemic has impacted the mental well-being of many people across the globe and now more than ever, there is a need to seamlessly monitor the negative impact of everyday stressors on one’s cognitive function,” says Rose Faghih, an associate professor of biomedical engineering who developed MindWatch in six years. “Right now MindWatch is still under development, but our eventual goal is that it will contribute to technology that could allow any person to monitor his or her own brain cognitive arousal in real-time, detecting moments of acute stress or cognitive disengagement, for example. “At those times, MindWatch could ‘nudge’ a person towards simple and safe interventions — perhaps listening to music — so they could get themselves into a brain state in which they feel better and perform job or school tasks more successfully, professor Faghih added. The specific tests used in this study involved a working memory task, called the n-back test which involves presenting a sequence of stimuli to the participants, in this case, images or sounds. It was shown one by one, and people were asked to indicate whether the current stimulus matched the one presented "n" items back in the sequence. This study employed a 1-back test — the participant responded "yes" when the current stimulus is the same as the one presented one item back — and a more challenging 3-back test, asking the same for three items back. Three types of music were also tested out, there was energetic and relaxing music familiar to the participants, as well as novel AI-generated music that reflected the subject’s tastes. Results showed that familiar, energetic music led to the best performance, followed by AI-generated music tailored to the participant’s taste. Coffee and perfume had lesser but still noticeable positive impacts. The MindWatch team wish to conduct further experiments to confirm the tool’s reliability and understand the broader effectiveness of various interventions on brain activity. Researchers have noted that while specific interventions might generally boost brain performance, individual results may vary. The study is published in the journal Nature.
