Product Overview


  • Fortified with Biotin, Panthenol & Proteins
  • Strengthens & Volumizes Fine Hair
  • No: Parabens, SLS, Petrolatum, Artificial Colors or Phthalates

Our rich lathering, body-building shampoo uses gentle botanical surfactants to thoroughly purify the scalp and cleanse the hair of dirt and oil. Hair-strengthening Biotin and Panthenol wrap around the entire hair shaft to boost volume and increase hair cortex elasticity for less breakage. Plant proteins add luster and bounce. Your hair looks and feels naturally thicker, with a healthy shine.

Born in 1959, Jason was one of the first to offer personal care products without harsh chemicals. For over 50 years, we have delivered safe, wholesome, no-nonsense products that happen to really work. Our formulas don't contain petrolatum, sodium lauryl or laureth sulfates (SLS), parabens, or phthalates. And we never test on animals. We invite you to try our entire line of safe, effective, body-loving products.

Suggested Use

On wet hair, gently massage shampoo into hair and scalp. Rinse and repeat if desired. Follow with Jason Thin to Thick Extra Volume Conditioner.

iHerb Customer Reviews

Probably the worst shampoo I've ever used - and I tried a looooot of different products.

It leaves my hair greasy and dirty looking. No matter how much I rinse it remains sticky. Because I didn't want to throw it away so I occasionally use it as a shower gel.

disappointed - خاب ظني في المنتج

Posted by MariamD on Sep 17, 2016

I've used this product for almost 7 months , three times a week , i hoped this shampoo along with the conditioner would help me with my hair . sadly it didn't , my hair falling became even worse , not to mention how it dried out my hair,badly,leaving me with another problem to worry about. ,it didn't work for me, "may" work for others , but don't expect Miraculous results. لقد ابتعت هذا المنتج على أمل أن يعالج شعري , استخدمته لمدة7 أشهر , 3 مرات أسبوعيا , كنت فعلا أتوقع أن أرى تحسناً , للأسف حدث الأسوأ ,أصبح شعري يتساقط أكثر وأكثر ,وقد جف شعري جدا وأصبح في حالٍ سيئة بالرغم من استخدامي للبسلم - المرافق له , لم أنهي العبوة اضطررت أن أوقف استخدامه وأن أبدأ في رحلة علاج للتلف الذي سببه هذا المنتج لم يفدني هذا المنتج ربما يفيد غيري "نوعا ما" , لكن لاتتوقعوا أن تحصل معجزة "thin to thick"الـ .
