First stop Kelp tablets which you can find in Holland & Barrett , for a reasonable £4.89. There's no solid scientific evidence it boosts hair growth but I've used it in the past and hair seemed to have a bit of a spurt South. Plus she of the glossy, long locks Jennifer Aniston is rumoured to have used Kelp to boost her hair growth in the past. Take note.
Biotin is another supplement found on the shelves of the local natural health store that can encourage your hair to get up off its follicle and grow. In fact biotin deficiency has been scientifically linked to hair loss, so it's well worth a daily dose of this B vitamin if your mane isn’t looking its best. When ingested biotin reacts with cell enzymes playing a vital role in producing amino acids, which in turn help to build protein within the body. And it’s the protein called keratin that makes up our hair and nails. Biotin is so clever in fact it can actually increase the elasticity of the hair's cortex – so not only does it strengthen our tresses it prevents them breaking too. Biotin tablets, £4.35 at Holland & Barrett .
If you want to call in the big guns then you need superstar Trichologist Philip Kingsley. I'm a big fan of his PK4 Supplements, £22 (at John Lewis ), that are 100% protein. Over a period of 4 months, taking the pills 4 times a day (hence the name, PK4) they work to strengthen your hair from the inside out. I've heard and seen these supplements do great things for a lacklustre head of hair.
Finally, Boots now stocks Nanogen Intervention 1 Month Supply, £39.95, this course of tablets contains biotin and amino acids, along with antioxidants to protect the hair and follicles. Like biotin iron deficiency has been linked to hair loss so these tablets contain the mineral for good measure.
