La Roche-Posay Anthelios Melt-in Milk Sunscreen SPF 60
₹2,490
SPF does not scale the way people read it: SPF 30 blocks about 97 percent of UVB and SPF 60 about 98, so doubling the number buys one percentage point.

| Specification | Olaplex No. 4 Bond Maintenance Shampoo 250ml | La Roche-Posay Anthelios Melt-in Milk Sunscreen SPF 60 |
|---|---|---|
| Price | ₹2,950 | ₹2,490 |
| Key actives | Bis-aminopropyl diglycol dimaleate | Avobenzone 3 percent, homosalate 10 percent, octisalate 5 percent, octocrylene 10 percent |
| Volume | 250 ml | 90 ml |
| Fragrance | Fragranced | Fragranced |
| Mains voltage | Not applicable | Not applicable |
| Period after opening | 12 months after opening | 12 months after opening |
| Warranty | 1 Year Official Brand Warranty | 1 Year Official Brand Warranty |
| Colour safe | Yes | not published |
| Cost per wash | 250 ml is roughly 25 washes | not published |
| Finish | not published | Milky, absorbs without a white cast |
| How it works | The active reconnects broken disulfide bonds in the hair's keratin. That is a genuine chemical repair, not a coating | not published |
| How SPF scales | not published | Not linearly. SPF 30 blocks about 97 percent of UVB and SPF 60 about 98 percent. Doubling the number buys roughly one percentage point |
| Reapplication | not published | Every 2 hours in sun, and after swimming or heavy sweating |
| Sulfate free | Yes | not published |
| Usage | It is a shampoo, not a treatment. The No.3 treatment is the concentrated product | not published |
| UVA | not published | SPF measures UVB only. UVA causes most ageing and tanning and is rated by the PA system, which US-labelled sunscreens do not carry |
| Water resistance | not published | 80 minutes, which is a tested claim rather than a marketing one |
| What actually matters | not published | Quantity. SPF is measured at 2 mg per square centimetre, about a quarter teaspoon for a face, and almost nobody applies that much. Applying half gives far less than half the rated protection |
| What it does not do | Nothing for split ends, which are mechanical damage and can only be cut | not published |
| Who needs it | Chemically treated hair -- bleached, coloured or permed. Virgin hair has few broken bonds to repair | not published |
Every row is a figure one or both products record. A blank is a figure the catalogue does not hold, not a zero.
