About
Tennille Hash serves as Paramedical Aesthetician, Master Esthetician and Master Lash Artist at Glow Skin Science, where she is the skincare lead. She has held an Aesthetician license since 2005 and also holds a Master Esthetician license. Not long after that, she became one of the first certified lash artists and sugaring specialists in Washington State.
She has earned more than 40 advanced certifications covering a wide range of techniques and concerns, from peels and microneedling to plasma-based treatments and conditions such as acne, rosacea and melasma. She is a Certified Acne Expert and works with clients through the business's acne program. She keeps up professional training every month, and her advanced skin treatments are carried out under the supervision of a Medical Director.
In 2010 she opened her own salon and day spa, where she recruited, trained and managed a team of estheticians, massage therapists, hairstylists and nail technicians. After years as a spa owner, she narrowed her focus to skincare treatments alone.
Her lash credentials include certification as a 4x Xtreme Lash Certified stylist and more than 100 hours of training in volume lash application. She trains other lash artists and has hired them.
Clients who want healthier, more confident skin work with her, and she tends to spend time going over the options before a plan is set.
