With #hairgrowthproducts hitting 60.7 thousand posts on TikTok alone, there are products out there that can take your locks from lacklustre to luscious - and all within your everyday hair-wash routine. From specialist shampoos and moisturising conditioners to replenishing hair masks and hair growth serums, find the formula to get ahead of your haircare needs.
Look for a hair growth oil that contains essential oils like Rosemary, Argan, Tea Tree or Peppermint, our fave ingredients for stimulating hair health naturally. If you want rapid results, combine Rosemary oil for hair with a barrier oil (try Coconut) and give yourself a relaxing scalp massage while you soak up the goodness.
Want to know how to speed up hair growth? Firstly, try regular scalp massages. Not only do they feel good, they also do good, stimulating hair growth by improving your general scalp health and circulation - sign us up.
Secondly, remember it's all about nourishing from within. Nutrients like Iron, Zinc and Vitamins A, C and E all help maintain healthy hair growth and encourage Keratin production. Make sure you're eating your five-a-day, plenty of protein and handfuls of whole grains to glow from the inside out.
And, of course, try adding a hair growth oil, serum or mask to your routine. Look out for the hair growth products with key ingredients like Biotin, Caffeine, and Hyaluronic Acid, which will all super-charge your strands.
The misconception with most hair growth products is that they solely focus on growing your hair longer - and faster. But they also work to thicken your hair, stimulating strands to grow out as well as down, meaning fuller, thicker, more voluminous locks. Choose a hair growth serum rich in both Biotin and Hyaluronic Acid to act as a densifying duo.
You may believe that hair grows faster in winter (we wish it did!) but, rather than seasonal changes, hair growth is mostly influenced by genetics, hormones, and overall health. However, a few factors that could contribute to hair growth in winter include increased blood circulation to the scalp in cold weather, less sun exposure minimising UV damage, and better hair care routines.
Can hair grow back after thinning? The answer is yes. By incorporating a hair loss treatment into our daily routines, we can encourage fuller, thicker hair once again. If we strike the balance of nourishing nutrients and powerful ingredients, it is possible to reverse hair loss or thinning, which does wonders for your crown - and your confidence.
