I know there are lots of questions on this site regarding head retention, but I feel like none of the answers are helpful.

I recently made a hefeweizen. 50% wheat malt, 50% pilser malt with about 13-14 IBUs. The beer turned out great except that it has zero head retention. I get a thin layer of foam that dissipates in 5-10 seconds. I have had this problem in the past and I've tried all the traditional advice but nothing seems to help.

Still, I must be doing something wrong.

Brewing process:

• Single infusion mash at 67 C (~152 F).
• 90 minute boil with all the hops added after 30 minutes.
• Cooled quickly with my counterflow chiller, takes about 10 minutes.
• 30 second burst of pure O2
• Pitched a 3 liter starter of WLP380. Wort temp at about 13 C (~55 F).
• Fermented at 15 C (59 F) for one week, then left it for another three weeks at 20 C (68 F) to finish and get rid of the sulphur smell.
• Bottled using 7 grams of table sugar per liter wort.
• The bottles have been at room temperature for four weeks now. They are well carbonated and taste great.

Cleaning:

• My kettle, mash tun and all other equipment is soaked in PBW solution for about an hour after each use, then thoroughly rinsed off using hot tap water and a soft brush. I've made sure there's no PBW residue left.
• My fermenter is also cleaned using PWB, rinsed with tap water, then sanitized with star-san solution. I leave the fermenter filled with star-san at least 30 minutes before transfering the wort.
• I clean my bottles using PBW too. I soak them for 10 minutes and clean them with a bottle brush. Then I rinse them with water and sanitize with star-san solution. I leave them to dry on a bottle tree.
• My beer glasses are cleaned by leaving them in PBW solution over night, then cleaned with a dedicated soft brush, rinsed with hot tap water and left to air dry on a rack.

Things I've tried:

• Adding a bit of cara foam malt: No visible effect.
• Ordered a water quality report: My tap water is clean and very low on minerals.
• Switching to a different brand for my ingredients: No visible effect.

Has anyone here had similar problems in the past? I feel like I'm out of things to try.

So, to sum every thing up:
