How Jennifer Anniston’s LolaVie brand grew sales 40% with CTV ads

For its first CTV campaign, Jennifer Aniston’s DTC haircare brand LolaVie had a few non-negotiables. The campaign had to be simple. It had to demonstrate measurable impact. And it had to be full-funnel.

LolaVie used Roku Ads Manager to test and optimize creatives — reaching millions of potential customers at all stages of their purchase journeys. Roku Ads Manager helped the brand convey LolaVie’s playful voice while helping drive omnichannel sales across both ecommerce and retail touchpoints.

The campaign included an Action Ad overlay that let viewers shop directly from their TVs by clicking OK on their Roku remote. This guided them to the website to buy LolaVie products.

One Control Is Never Enough

Relying on a single protection — firewall, MFA, or antivirus — creates a fragile defense. When that layer fails, everything behind it becomes exposed.

Layers Must Be Independent

True defense in depth means controls don’t rely on each other to function. If one system is bypassed, the next must still operate effectively.

Redundancy Without Strategy Creates Complexity

Stacking tools without integration increases noise and operational burden. More vendors don’t equal more security — coordination does.

Detection and Prevention Must Coexist

Prevention blocks known threats. Detection identifies unknown or evolving ones. Both are essential — neither replaces the other.

Human Oversight Is Still a Layer

Processes, approvals, and verification steps are part of your defense model. Social engineering bypasses tech — but struggles against disciplined culture.

Review Your Stack Like an Attacker Would

If you compromised one layer, what would stop you next? Map your controls from breach to recovery. Defense in depth only works if every layer is tested.
