BASED Leave-In delivers real results - clean & effective ingredients, real hydration & definition. Zero shortcuts, zero compromises.

If you want softer, healthier-looking, easier-to-manage hair - yes. BASED Leave-In deeply hydrates, helps protect, and helps strengthen your hair between washes. It's your shield.
Will it weigh my hair down or make it greasy?

Is it safe for daily use and color-treated hair?
Yes. It's gentle, pH-balanced, and formulated without drying alcohols, parabens, or silicones - gentle on color-treated hair.

Does it contain silicones or synthetic fragrance?
Zero. Like everything BASED, it's free from silicones, parabens, and synthetic fragrance. It's lightly scented with our naturally-derived fan-favorite scent Santal Sandalwood: Masculine, clean and addictive.
Can I use it with other styling products?
Yes, BASED Leave-In works great by itself but we always encourage mixing & matching different product combos to see what works best for your hair. One popular combination is the BASED Curly Duo , which is a mix of BASED Leave-In Conditioner and BASED Curl Cream.

My Truthful and Honest review of Based as a first time customer from Ireland…
Based saved me, went from having parched, frizzy, dead curls and an extremely dry scalp using my Proctor and Gamble shampoo and conditioner to having hydrated, lush, defined curls and a healthy scalp with Based. To be honest, the price is quite hefty but truly worth every cent. I have never seen any result similar with alternative brands that even scores 70%+ on Yuka… just buy it, you will not regret!!!

The leave in conditioner is very hydrating and goes very well with the mousse. The only issue i can see is that it could weigh your hair down if you have wavy hair and use too much, but aside from that its a very good product

Not gonna lie, I was a bit skeptical at first. But, when it arrived, I tried it out and the leave in conditioner really gave my hair moisture and volume. This is a really good product I recommend.
