'My hair is growing really fast' - shoppers snap up hair tonic available on Amazon

Weleda is most known for its cult status Skinfood range; however, the brand also does hair care products. One of them is very popular - especially among shoppers hoping to grow their locks. The Revitalising Hair Tonic is made for people who are having issues with hair thinning, hair loss, and a flaky scalp.

The tonic contains rosemary leaf oil, an ideal alternative to hair growth serum. According to the instructions, you are meant to apply the tonic twice daily - once in the morning, then again at night. You can buy it from Amazon for £10.46, down from £14.95. The tonic is also vegan, containing no animal extracts.

More than 2,000 bottles have been bought on Amazon in the past month alone. The tonic has more than 7,000 customer reviews. One customer wrote: "Probably the only product I have used so far that works. I definitely have more hair growing and my hair is also growing really fast."

A second added: "Excellent product. Highly recommended if you want to improve the condition of your long hair and reduce fallout. Arrived in good time. Very happy with the item and customer service. Thank you." A third said: "I had thin hair due to hair loss. After using this twice a day religiously, I saw hair grow thicker. There's a nice smell to it. After two days, I wash my hair as my hair tends to get greasy."

A fourth commented: "This makes your scalp feel amazing. Gorgeous fresh smell. I use it with the Denman D3 brush every night. I found it helpful to put it in a spray bottle so there is less waste, and it goes exactly where you want it. It has made my hair grow very quickly around my hairline which is perfect. I would totally recommend it. Just bought some more."

A fifth pleased buyer wrote: "Hair loss has decreased significantly and my scalp feels very comfortable and is no longer irritated. Highly recommended." Not all customers were impressed, with one saying it hasn't made a difference. They explained: "Sadly this product did not work for me. After four months of using it twice a day I see no difference at all. I was hoping to see some difference. So I cannot recommend it."

Another said it made their hair dry, writing: "This product dried my hair out made it look like straw also gave me an itchy scalp." Other hair loss treatments include the Regaine for Men Extra Strength Scalp Foam, £55 from Boots. You get three months' worth of products in the pack. If smoother locks are your goal, then you can buy a bumper bottle (100ml) of the iconic Moroccanoil's Hair Treatment at Superdrug for £60.99.
