Women and children of Ethiopia's Daasanach tribe turn old bottle tops into hair ornaments
The look varies: younger girls and children get the most basic version of the wig, while the oldest women are treated to the heaviest numbers with the most embellishment.
Men are only allowed to wear the bottle top wigs until they marry - after that, they create small clay headpieces decorated with a colourful harlequin pattern and enlivened with a feather, although the latter is only allowed after a hunt or a successful clash with an enemy.

Looking good: Children are also allowed to wear the elaborate headpieces but adult men are not
Those enemies come from a tribe living further down the Omo Valley in Kenya, the Turkana people, who like the Daasanach, are cattlemen willing to rustle, raid and even kill to expand their herds.
In this, they aren't alone. From Uganda's Karamojong to Kenya's famous Masaai and Samburu peoples, cows are treasured along the length and breadth of the Rift Valley.
The 20,000-strong Daasanech are one of a cluster of traditional tribes living at the Ethiopian end of the valley, albeit close to the Kenyan border and the enormous Lake Turkana.
Despite the proximity of the lake, water has to come from the Omo River: Turkana is the world's fourth-largest salt lake and one of the few to exist permanently in a desert.
Time consuming: Each wig takes weeks to make, even after enough bottle tops and beads have been found
Colourful: Many of the young women combine their bottle top wigs with piles of colourful beads and lip piercings made from grass
Getting in on the act: Boys enjoy dressing up in necklaces and beads too but the wigs go once they reach adulthood
Income: Many of the women make extra cash by making jewellery but according to Eric Lafforgue, refuse to sell their wigs
Heavy: The oldest women wear the biggest and heaviest headpieces, as well as stacks of colourful beads
Matching: Bottle tops are popular because they're colourful and sound good during dances
Spectacular: Elderly ladies get to add unusual extras such as old watches and feathers to their wigs
Keeping it tidy: Because the wigs are often attached to the hair itself, the Daasanech sleep on neck pillows to keep it all tidy
For the Daasanech, the harsh landscape and burning heat makes moving around in search of grazing a necessary part of life with the result, says Eric Lafforgue who took these incredible photos, that their villages 'resemble refugee camps most of the time'.
Just as they will use any sparkly item available to make their wigs, so they use anything that comes to hand - whether bits of old plastic or tufts of tumbleweed - to build their small dome-shaped homes.
Most of their income comes from tending their herds while women supplement their cash reserves by making jewellery. They won't, however, sell their elaborate wigs.
'They become part of them,' explains Lafforgue. 'They are part of their identities.'
Much of the unsold jewellery is worn by the older women who can bear the weight of all the beads, caps and bits of metal because most of the heavy lifting is done by younger girls.
'The younger people look quite androgynous,' says the photographer. 'The young men love to wear necklaces and earrings while the girls have bigger muscles because they do the most difficult work like carrying water.'
Regardless of gender, the men's clay buns and the women's bottle top hairstyles mean that everyone uses a neck pillow when they sleep. 'These looks take weeks to make,' says Lafforgue. 'There's no way they'd ruin them just for a nap.'
Fashion: Lafforgue says combining a bottle top wig with an animal skin apron (cheetah left, colobus monkey right) is very popular
Plain: By contrast, men wear small clay wigs atop buns and can decorate them with feathers if a hunt has gone well
Pared down: Although men aren't allowed to wear the bottle top wigs, they do get to wear jewellery such as necklaces and earrings
Welcome: A group of Daasanech children performed a welcome dance when Mr Lafforgue arrived in their village
Recycling: Most of the small dome-shaped homes are made with whatever is to hand giving it the look of 'a refugee camp' says Lafforgue
Fresh water: A group of tribesmen pull up their canoes on the banks of the Omo River - the main source of water for the Daasanech
On their way: Lafforgue was ferried across the river by one of the tribesmen in his homemade canoe
