近些年来，生育率降低，幼儿园一家接一家地倒闭，从前鳞次栉比出现的教培机构也迎来了行业寒冬。 理发这门手艺较少存在于主流教育体系中，连在中专和技校都比较少见。 当专家们都在预测未来业界经济走势，衰败场景会击鼓传花到哪个行业时，有这样一个和老百姓们生活息息相关的行业悄悄走向转变，就是美发行业。 无论身处何样环境阶层，总得理发。无论是坐进装修豪华的理发店里，被销售推荐各类会员产品充卡折扣，还是在街边树下被老师傅亲手修剪头发，理发这 事对大众来说都不陌生，是生活所需。 谁也没想过，理发行业也能开始衰败。明明还未和电商进行正面交锋，就缓慢地死在了电商时代。原因是什么呢？ 倒是有不少培训学校，教美发美容，护理保养，只是教育水平各不相同。进入这样培训学校的学生往往面临初高中课程学习吃力的情况，是老师同学眼里 的"差生"。 学习成绩落后，至少要学门手艺。他们有的确实也认真学习，因此能够养成独特审美观念，能为不同顾客定制专属风格的剪发烫发等方案。当他们把设计和 实操过程发在自己自媒体的帐号上，往往能迅速火起来，收获几十万甚至上百万的赞。 还有人专程跑去几千公里外的地方找他们美发。 可这样精通美发这门技术的人实在是少数。大部分从 ...
