I would like to know about wellastrate and the differece between wellastrate and xtenso and regular relaxer, which one is less damaging for hair, what is the difference between hair straightner and hair relaxer? have you heard of wellabalsam I was told that it is the best conditioner, and I heard all german products are fantastic is that true? and if it is do we have german stores in north america? I would like to know how wellastrate and xtenso are apllied? Do they have to be applied by a professional (how much is that) or I can just do it at home? Thank you
