'While the boys walk on cows, Hamar women accompany him: they jump and sing,' reveals Lafforgue, who witnessed a ceremony.
'The more abundant and extensive the initiate’s scars are, the deeper the girls' affection is to the boy who is about to become a man.
'Totally committed to their initiated sons, the mothers are whipped to blood, in order to prove their courage and accompany their sons during the test.'
But for Hamar women, beatings are not just part of an initiation ritual - they are daily life until at least two children have been born.
Under Hamar rules, a man need not explain why he's delivering a beating. It is his prerogative to mete out as he sees fit.
Men can also have more than one wife, with junior wives left to do the lion's share of the planting and water gathering.
'They do not have really the choice,' says Lafforgue. 'As [with] many women in Africa, they carry water, wood, take care of the food and the kids, while the men take care of the cows - the Hamar treasure.
'Hamar men can have several wives,' he adds.'The Hamar women who are not a first wife have a really hard life and they are more slaves than wives.
'[But] seeing those women with their animal skins, their special hairstyles, and their body covered with this orange make up was fascinating.'
' I always take photographs for two reasons,' he explains. 'First, providing a testimony as many tribes are starting to disappear but also to show the world how other people live, even if some of the time they have shocking practices.'
He tells the story of meeting a Hamar boy who had walked for several days to a local town, just to see his favourite Premier League football team on television.
'This guy was wearing a Chelsea T-shirt, but still had to jump over ten bulls to be able to marry a girl in his tribe: a real culture shock.
'They are all really into Chelsea, Arsenal, like many other Ethiopians, who are just crazy about English football'
With more and more Hamar swapping traditional life for Arsenal shirts, the days of beatings and cattle jumping would appear to be numbered.
FROM BEATINGS TO BEAUTY: ETHIOPIA'S HAMAR PEOPLE AT A GLANCE
Most still live in traditional villages, although growing numbers are migrating to the region's cities and towns as well as the Ethiopian capital, Addis Ababa.
Cattle form the axis around which the Hamar's world revolves, evidenced by the fact that there are 27 different words to describe the colour of a cow in the local language.
Men spend the majority of the time caring for the animals, which are also used to pay bride prices when the man takes a wife - always a woman from the Hamar tribe - and generally amounts to 30 goats and 20 cows.
Cows also form part of the male initiation rite, which involves contenders attempting to leap over a row of 15 cows made extra slippery with dung. At the same ceremony, the man's sisters and other female relatives are beaten bloody to create a blood debt so the man remembers to help them should they face tough times in the future.
While cattle-leaping is relatively harmless, another practice, known as 'mingi' is more troubling. 'The Hamar tribe still practises ritual infanticide,' Lafforgue explains.
'If the first tooth appears in the upper jaw, instead of the lower, the child becomes what they called 'mingi' - this applies also to the baby teeth and the adult teeth when the kids are seven or eight.
'If a 'mingi' child is kept in the village by the mother, elders believe droughts, famines and diseases will come in the community, so they kill the babies.
Most 'mingi' children are left in the desert alone to die, although local charities now regularly check the area for abandoned children which are then raised in orphanages away from the tribe.
