Se siente la calidad y la relación con el precio, tiene un aroma sutil pero bastante agradable y rico, he notado que mi cabello sí creció mucho más rápido (como dos centímetros en 1 mes) y bastante bien, no deja reseco ni grasoso el cuero cabelludo y se siente bastante suave en el cabello, lo utilizo en conjunto con un cepillo especial para dar masaje en el cuero cabelludo, tiene sulfatos; por lo que si acabas de salir de una decoloración, te recomendaría que primero utilices un shampoo enfocado en reparar tu cabello e hidratarlo, aún así, después yo lo comencé a utilizar y me deja el cabello súper lindo. Noté que me aporto también mucho más volumen, pero nada de frizz. Tardó un poquito en llegar pero en excelentes condiciones.

Wonderful, leaves my hair feeling great for days, and my hair feels very healthy with minimal shed. Friendly to coloured hair. After running out of this I purchased the 1000mL bottles from a local salon shop. You can add water to the remainder of your bottle to get all of the product out, though I had to pour it in from the top as the bottle is very difficult to take apart. You do not need a ton, about a quarter size drop and you should have enough for your roots. Shampoo foams up nicely, conditioner stays slick. Does not seem to cause me any skin issues and I have fairly sensitive skin and an acne prone chest/back. One note: product is unfortunately not cruelty free, but I have not been able to find a cruelty free product that compares.
