外出要搽防曬大家都知！你有聽過外出要保護秀髮嗎？
誰不喜歡在風和日麗的白天擁抱大自然、到戶外參加各種精彩活動，度過美好時光？但長期處於戶外，原來有很多不可控因素會導致頭髮受損！例如來自太陽的紫外線、大風所導致的水分流失、泳池水所產生的化學物質、海洋中的鹽分、體育活動中的汗水和污垢等等，都是導致頭髮損傷的元兇。
Holistic Hair 整合了有 5 個快速的護髮小貼士，讓頭髮盡量免受外在環境或污染影響，保持頭皮健康！
1）戴帽！
沒有什麼比戴帽更能保護頭皮和頭髮免受陽光照射！香港夏天熱到似熔爐，長時間暴露在太陽的紫外線（UVA 和 UVB）下，會灼傷頭皮，並損壞頭髮的從角質層甚至其內部結構！太陽光還會損壞頭髮中的色素和蛋白質。如在陽光下不加以保護，天然黑髮會呈現微紅色，漂染過的頭髮會加速變黃、變暗和褪色。戴一頂帽子，除了增加造型感，原來是真的能「護髮」！
2）使用優質、天然植物護髮素
戴帽很有用，但不會令頭髮免受泳池中的化學物質、海洋鹽分或無情風的影響。想保護頭髮免受這些元素影響的好方法，是選擇一枝安全、無害、零負擔的護髮素！如進行戶外活動，出門前若有時間，先洗一次頭並且使用天然護髮素，護髮素成分當中如添加優質天然植物油，是可以完美地滋養頭髮（沒錯！即使頭髮已經過水洗走護髮素，護髮素因子依然能覆蓋及保護赤裸的秀髮），有助於減少鹽水、化學物質、污垢的吸收，並鎖住急需的水分！
3）長髮請綁起
太長的頭髮一年四季都難應付，需要特別注意，尤其戶外活動時遇上大風吹！由於風會令秀髮水分悄悄流失、導致纏結、分裂。對抗風吹損傷的好方法是適量使用護髮素，然後在出門前將頭髮鬆散地編成辮子，但切忌太緊地綁於頭上，減少風接觸秀髮。因為有證據表明，髮髻綁得太緊，隨著時間的推移，也會對毛囊造成壓力，從而導致脫髮！
4）在戶外度過一天後，盡快洗頭！
第二天洗頭是很吸引，但對油性頭皮從來都不是一件好事。研究表明，大汗腺（集中在有毛囊的地方的單管狀腺）的汗液含有乳酸、尿素和其他物質，使汗液成為壞菌完美溫床的聖地！它是一種脂肪分泌物，有可能散發出難頂氣味。此外，細菌與污垢、塵垢或化學物質的結合會導致瘙癢、頭皮屑等令人不快的情況。所以洗頭很重要！也不要忘記使用護髮素來閉合角質層，增加光澤。每週定期使用護髮膜或護髮調理油也有助讓頭髮保持最佳狀態。
5）蘋果醋對抗環境壓力
含有蘋果醋的頭皮護理平衡液平衡頭皮pH 值，舒緩敏感症狀，防止不必要的頭皮感染，並關閉頭髮上的角質層以改善秀髮光澤。用於洗頭水和護髮素後，有助解決因環境壓力引起的各種頭皮問題。
外出享受美妙的戶外活動前，記得為頭髮設想一下喔！
5 Quick Hair Tips to Protect your Hair Outdoors
We all love to spend time in the great outdoors, embracing nature and participating in our favourite activities. Regardless of where we might be, or what we are doing, it's important to think about how we should protect ourselves from the elements and what we can do to maintain that beautiful head of hair.
Yes, we are talking about UV rays from the sun, loss of moisture from the wind, chemicals from swimming in pools, salt from the ocean, sweat and grime from sports activities and the list goes on.
So how do you look after your crowning glory, that unruly mane that just seems to need constant attention?
Here are 5 Quick Hair Tips, to keep your scalp healthy and your hair protected from the elements.
1. Wear a hat
Nothing beats wearing a hat to protect your scalp and hair from the sun. Prolonged exposure to the sun's ultra-violet A and B (UVA and UVB) rays can burn your scalp and damage your hair from its cuticle to its inner structure. The sun's rays can also damage colour pigment and protein in the hair. Natural brunette hair can develop a reddish hue if left unprotected in the sunlight and chemically treated hair can yellow, dull and fade. So choose a hat that covers all of your hair and tuck longer locks underneath it.
2. Use a natural plant based conditioner to protect your hair
But, a hat won't protect your hair from the chemicals in a pool, the salt from the ocean, or the unforgiving wind, so a great way to shield your hair from these elements is to apply a natural, plant-based hair conditioner, just before you go out. Use it like a lotion for the hair and re-apply if needed. The great thing about using a conditioner with natural plant oils is they coat and nourish the hair, helping to reduce absorption of the salt-water, chemicals, grime and locking in that much needed moisture.
3. If you have long hair braid it
Long hair requires some extra attention all year round. It can be prone to splitting, through loss of moisture, and tangling, due to the wind. A good way to combat both, is to add the conditioner and then loosely braid the hair before you go out. Don't tie it up tightly, or high on the head, as there is evidence that over time this can cause stress on the hair follicles, which could lead to hair loss.
4. Wash your hair as soon as you can following a day in the great outdoors
Yes, it's tempting to leave washing your hair to the following day, but it's never a good thing. Research shows that sweat from the apocrine glands (which are concentrated where there are hair follicles) contain lactate, urea, and other substances which make this sweat a perfect environment for the wrong bacteria. It's a fatty secretion and has the potential to be quite odiferous too. Added to this the bacteria in combination with dirt, grime and other chemicals can cause itching, dandruff and other unpleasant conditions. Wash your hair with a natural, plant-based shampoo and don't forget to use conditioner to close the cuticles and add some shine. A hair mask is a deep conditioning treatment and used once a week will really help to keep your hair in top condition.
5. Use a finishing rinse
A finishing rinse is generally speaking designed to normalise the scalp pH, soothe and protect from unwanted infection and close the cuticles on the hair to improve shine. Used as a leave-in product and following the shampoo and condition treatment, a finishing rinse goes a long way to addressing issues caused by constant environmental stressors.
So get out there and enjoy the great outdoors. Hope these tips help!
