I suffer from thyroid disease and one of the symptoms is hair loss and very flat brittle hair. I bought Garnier Fructis Body Boost Volumnizing Spray on a whim one day to see if it could do anything to make my hair look fuller and like I had more volume. I originally only sprayed it on my roots and hanging my head upside down blow dried it dry to help my hair stay boosted up. I was amazed after using it that first time that it actually boosted up my flat hair and gave it volume around my scalp. I have since tried it on my entire head of hair when my hair was wet, just letting my hair air dry it still gave it an awesome boost of volume. I am so happy to have found this product, no more lifeless stuck to my scalp hair. It gives my hair the boost it needs and still leaves it manageable and soft. Garnier Fructis Body Boost Volumnizing Spray also smells amazing. No chemical smell at all to this stuff, just citrus and flowers.
