I really like Revitalash. It's kind of middle of the road in terms of price, and it was really effective for me. I've tried the Ardell eye/brow conditioner and it didn't do anything.

Try EnvyDerm Eyelash Enhancement and Conditioning Black Volume Mascara. It conditions and grows your lashes. Also, EnvyDerm uses only all natural products. I have it and it really works. I also have the Volumizing Lip Plumper in Peachy Nude and my lips look amazing!
