Hair supplement brand New Nordic has partnered with US influencer Alexis Ren to promote its products.
Ren will offer consumers 20% off the brand's Hair Volume supplements on her Instagram page @Alexisren, using the code ALEXIS at hairvolumeofficial.com.
She said: "After four weeks I’ve seen a noticeable difference. My hair has become stronger and grows faster than normal.
"Taking Hair VolumeTM is an easy way for me to keep my hair strong and healthy – and Hair VolumeTM also helps strengthen my nails.”
The supplements are the first to contain natural apple proanthocyanidine-B2 growth factor, according to the brand.
The Swedish apple and millet formula also contains amino acids, silica and vitamins, which are claimed to support health hair volume and growth, as well as skin and nails.
The products are sold in more than 30 countries.
