Get a FREE Redken Acidic Grow Full System
Scalp & Hair Serum Sample
A salon-quality scalp serum — worth $38 — shipped to your door for free. Here’s exactly how to trigger the ad and claim yours.
How to Claim Your Free Sample
This freebie is delivered via a sponsored social media ad — there’s no direct link. Click every button below and follow each step to trigger the ad in your feed.
Follow Redken on Facebook & Instagram
Go to Redken’s official pages and hit Follow. Then like and comment on at least 10 recent posts on each platform. This tells the algorithm you’re interested in Redken — making the sponsored sample ad far more likely to appear in your feed.
Like & Comment on at Least 10 Posts
On both Facebook and Instagram, scroll through Redken’s recent posts and like and leave a comment on at least 10 of them. Comments carry more algorithmic weight than likes alone — even a simple “love this!” counts. Do this over 1–2 days for best results.
Search the Product on Google, Facebook & Instagram
Search “Redken Acidic Grow Full System Scalp Hair Serum” on Google and click through 2–3 results, spending 30–60 seconds on each page. Then search the same phrase inside Facebook and Instagram’s search bars. This cross-platform activity reinforces your interest profile and boosts ad targeting.
Also Follow Redken on TikTok for an Extra Chance
Some users have spotted the free sample ad on TikTok as well. Follow Redken there and watch a few of their videos to signal your interest. It only takes 30 seconds and gives you an additional channel where the ad may appear.
Watch Your Feed & Stories — Then Tap “Get Offer”
Now scroll through your Facebook and Instagram feeds — including Stories — at least once or twice a day. The sponsored ad will appear as a regular post or story with a “Get Offer” or “Get Sample” button. When you see it, tap immediately, enter your name and shipping address, and you’re done. No payment info required. Redken will mail your free sample directly to you.
- Interact with Redken posts before the sample period ends — the algorithm rewards consistent engagement, not just last-minute activity.
- Check your feed at different times of day — morning, afternoon, and evening. Ads rotate based on your activity windows.
- Don’t just like — leave genuine comments on posts. Comment engagement weighs more heavily in ad targeting than likes.
- If you haven’t seen the ad after 3–4 days, repeat Step 3 (searching the product name on Google and social media) to refresh your interest signals.
- Check both your main feed and Stories — the ad can appear in either location.
- Some users report seeing the ad on TikTok as well — follow Redken there too for an extra channel.
- If a friend already got the sample, ask them to share the ad post with you — sometimes that triggers it for others in their network.
